The Newly-Discovered Watches Of SEALAB III & The Records That Prove It

US Navy-Issued Doxas, Rolex, & A Complete Surprise

By Benjamin Lowry

The US Navy’s SEALAB experiments of the 1960s were pioneering attempts to prove man’s ability to live and work on the sea floor for an extended period, supported by a specialized underwater habitat. The techniques and equipment developed for SEALAB I, II, and III would later be used in shadowy underwater espionage targeting the Soviet Union, but SEALAB is better remembered to watch enthusiasts for some of the legendary watches used by some of history’s boldest divers.

In this Dispatch, I’ll share how a chance encounter with a piece of handwritten history forever alters our understanding of the watches of the Navy’s final SEALAB project.

For someone like me, the Man In The Sea Museum in Panama City Beach is something akin to paradise, providing one of the world’s most impressive collections of vintage military diving memorabilia, much of it related to SEALAB. Given the timing, SEALAB is associated with some of history’s great tool dive watches and played a key role in the development of the Rolex Sea-Dweller.

But, despite what the internet may say, Rolex isn’t the only name in the SEALAB game. Thumbing through old binders while volunteering in the museum’s library, I came across an issue log for dive watches hand-written in 1968 by a SEALAB legend. The usual suspects including Rolex were there, but the log also illuminated the outsized role played by Doxa as well as another Swiss brand I would argue no one would ever guess. In this Dispatch, we’ll look to archival evidence, interviews with surviving Aquanauts, and a few educated guesses to provide the most complete picture ever assembled of the watches of SEALAB III.

My dad and I were hard at work cataloging and organizing the library in the Man in the Sea Museum when we came across a document that stopped us in our tracks.

In this increasingly digitized world, there are still a few horological secrets lost to history waiting to be uncovered, the type of secrets that haven’t been converted to PDF. The same watch stories make the rounds again and again, some amazing discoveries are put forth by genuine horological enthusiasts, and some stories are haphazardly cobbled together by brands to help push more watches.

Most are somewhere in between. Watches have never received the amount of attention they do today. Record-keeping for the sake of enthusiasm or posterity was not common practice. This is also true in the arena of dive watches, fostering a healthy debate about the actual timeline of the introduction of the Blancpain Fifty Fathoms, Zodiac Sea Wolf, and Rolex Submariner, in particular.

Except when it comes to the military. In military settings and especially diving, recording every bit of minutiae is an occupational necessity, a matter of life and death in certain cases. Luckily, as a Coast Guard veteran turned commercial diver, it happens to be my area of interest, which is how I found myself volunteering to help organize the Man in the Sea Museum’s stacked but admittedly disheveled library a couple of years ago.

The Man In The Sea Museum is home to the original SEALAB habitat as well as an incredible library full of old US Navy records.

Leafing through records from the SEALAB programs, I came across a few scribbled lines on notebook paper that validated my years-long horological quest to understand the role of tool watches in the United States military, particularly in underwater applications. Along with these handwritten records, I uncovered hundreds of photographs from SEALAB that had yet to be digitized, and therefore, had yet to be seen by the watch community, until now. A dive watch enthusiast’s dream.

I went through binder after binder of records from all three of the Navy’s SEALAB experiments. I was looking for something that clued me into what equipment was used, particularly what watches were used. These aquanauts recorded everything. It was part of their job, of course, but the level of detail was staggering.

Finally, after hours spent carefully flipping through delicate aged paper and deciphering faded handwriting from the ‘60s, my efforts paid off.

A list of the exact watches that were used on SEALAB III. And when I say exact, I mean it—right down to the serial numbers. And it came directly from one of the aquanauts, meticulously detailed like everything else about the mission. While several watchmakers have established SEALAB connections—including an excellent article by Justin Couture detailing the role potentially played by Aquastar—some of the brands mentioned in the log had never really been in the SEALAB conversation before, let alone with hard evidence of being officially issued by the US Navy.

If I could, with the help of friends and former Aquanauts, prove the veracity of this hastily written log, our understanding of military dive watches would be forever altered. Here is the handwritten log that sent me so deeply down the rabbit hole.

The original handwritten log was reportedly penned by none other than Bob Barth, the only aquanaut to serve on all three SEALAB missions.

For the sake of legibility and to aid in deciphering the shorthand, I have—with help from surviving aquanauts—added some context to the list to help give us a better picture of who these watches were issued to.

Unsurprisingly, we see the usual suspects on the wrists of the aquanauts, starting with Rolex, although it’s important to note that what was sometimes recorded as Rolex was sometimes actually a Tudor Submariner, as Rolex took care of distribution and delivery. In ‘69, the US Navy had a contract with Tudor that had already begun in the late ‘50s, so there’s a chance these watches came from that procurement arrangement.

A brand associated with anything but diving in 2024, I was surprised to see Jaquet Droz mentioned in the issue log from SEALAB III.

Looking through the list, something else stood out immediately. “JK Droz” was listed in the records as having been issued to an aquanaut. Surely not the Swatch-owned atelier producing automatons that cost six figures and watches with all sorts of crazy enameling and decorations. Jaquet Droz isn’t a name you hear in the W.O.E. sphere often. The brand has never once been mentioned on this site before, and they certainly don’t fit in with the “Watches of Espionage” crop of brands.

As usual, there are layers to the story. But first, let’s look at the watches from brands we do know something about: Doxa and Rolex.

While Doxa has been loosely associated with SEALAB and Navy Divers in the past, the discovery of this document adds clarity to the brand’s official position as a US Navy-issued watch during the SEALAB experiments.

Digging deeper into the Doxa watches on the list, the brand’s serial numbering convention has been well documented by MKWS, a Doxa expert on Watchuseek. MKWS posits that Doxa introduced a 7-digit system where the first two numbers correspond to the year of production. In the case of all the models issued to SEALAB, that number is 66, which would suggest they were produced in ‘66, at least in theory.

Officially released in 1967, there are only a few other examples of Doxa Sub 300 models from 1966, meaning the US Navy was among the earliest adopters of the brand. If that’s not an endorsement for a new-to-market dive watch, especially when Navy Divers already had access to Rolex and Tudor Submariners, I’m not sure what is.

Interestingly, the only Rolex serial number listed also registers as being produced in ‘66 (Rolex serial numbers of that era aren’t an exact science, but can be traced to an approximate year of production). This all checks out, as the gearing up for SEALAB III would have taken place during this time. SEALAB II had been a successful mission in ‘65, and SEALAB III took some time due to engineering requirements and modifications that allowed the habitat to go significantly deeper than the previous two missions, 610 feet as opposed to 205 feet for SEALAB II and 192 feet for SEALAB I. The Vietnam War also put pressure on budgets for such a novel and costly project.

Much of the equipment and material—including watches—for the final SEALAB program was likely carried over from SEALAB I and II. After Doxa, the second most present brand appearing in the logs was Rolex, and the Crown had certainly been ever-present in underwater exploration for nearly a decade at the commencement of SEALAB III. Bob Barth, the only aquanaut to have dived on all three SEALAB missions, was reportedly instrumental in developing the Rolex Sea Dweller.

Barth dove with his Rolex Submariner on SEALAB I and II, so it’s no surprise to see several Submariners listed in the SEALAB III records. Another Rolex Submariner was issued to Leo Gies who is recorded on our list as having received a Doxa. Gies’s Submariner—which was sold by Bonhams on behalf of the Gies family in 2015—was engraved “SEALAB III” on the back, which makes its absence from our list all the more interesting. Maybe there is another handwritten log out there. Our research continues.

We’ll do another Dispatch on the role of Rolex in US Navy Undersea Research, but for now, let’s continue by discussing the role played by Doxa in the dive watch landscape of the late 1960s.

Doxa & Diving In The 1960s

Georges Ducommun founded Doxa in 1899, and the company quickly developed a reputation for producing a broad range of dress and sport watches—but the brand will always be best remembered for its contributions to the world of undersea timekeeping. In the 1960s, Doxa was one of the front-runners when it came to producing watches specifically for professional diving applications.

The “skin diver” category of watches was well established, with sporty watches suitable for recreational water activity. These came out of the recreational diving boom of the late ‘50s, but as diving equipment became more technologically advanced, so did the need for a watch that could handle significant depth and pressure, but more importantly, remain legible in murky water. This is where Doxa’s signature design element surfaced; the company found that a specific hue of orange was most visible underwater. The bright orange “Professional” dial became their calling card.

The Sub 300 and later 300T models emerged from Doxa’s design and field studies and quickly became a popular diving watch for professionals—the intended target segment, and the military alike. The Swiss Armed Forces purchased and issued this model to Swiss combat divers in approximately 1970. Bolstered by its inclusion in Clive Cussler’s thriller novels, the orange dial and “beads-of-rice” bracelet have become a common sight in recreational and military dive communities ever since. The model also became popular because it was championed by none other than French oceanographer Jacques Costeau.

With a better grasp of the brands and watches on the list, our next step was to track down and speak with the surviving aquanauts, one of whom provided a bombshell about the written log’s author. When we reached out to aquanaut Richard “Blackie” Blackburn, he took one look at the log and confirmed that it was the handwriting of none other than Bob Barth, the Bob Barth who helped create the Sea-Dweller, pioneering the use of a helium escape valve in watches in the process.

Barth was also, according to Blackburn, the man who kept track of where all the Navy’s Doxa Sub models and other watches were going. Unfortunately, Barth passed in 2020, so we weren’t going to be able to ask him directly about the log, but our research carried on.

It’s also important to note there is no mention of the Doxa Conquistador in our log, which is a specific version of the 300T equipped with a helium escape valve. For more on the rarest Doxa Sub variant, check out Perezcope’s research on Doxa’s role in developing the helium escape valve. Given SEALAB was a saturation diving experiment—the one environment where you need the valve—it would have made sense for Doxa to have sent over the Conquistador, but we found no definitive evidence of this being the case.

The next step was taking stock of exactly what was issued using the records and then matching those serial numbers with the watches on the wrists of aquanauts, if possible. It was time for the detective work. While many have passed—SEALAB III took place 55 years ago—five of the aquanauts listed in the log as the recipients of Doxa watches are still alive today. We started by tracking down their contact info and cold-sending emails to these legends of undersea exploration.

When I sent an email to Richard “Blackie” Blackburn with my number in the signature, my phone rang about two minutes later. After identifying the handwriting on the log as that of Bob Barth, Blackie informed me he had no recollection of ever being issued a Doxa. But, he said it wasn’t that unusual to see his name on the log, describing Barth’s issue process for watches as being as casual as “trading a cup of coffee” for a watch in certain instances before noting the transaction in his log with whatever name and number moved him at the time. Years later, Barth made up for it, gifting Blackburn a Rolex GMT-Master with his name and “SEALAB III” engraved on the caseback, a watch that he lost to a shady watch repairman years later.

Because of a photo circulating the web showing the former Royal Navy officer wearing a Doxa, I felt confident Cyril Lafferty, who was loaned to the US Navy SEALAB project by Her Majesty’s Royal Navy, might have the goods. While Mr. Lafferty confirmed he is the man in the photo wearing a Doxa, he said he had no recollection of being issued a Doxa watch or any other by the US Navy. He did remember being issued a Rolex or Omega by the Royal Navy, however. Later serving as the captain of the Royal Navy’s only deep-diving research vessel, HMS Reclaim, Lafferty went on to pioneer hyperbaric treatment techniques for multiple sclerosis.

In an email exchange with retired Captain Osborn, he confirmed he was issued a Doxa watch and wore it for all of the years he was an active Navy Diver before making the change to a Seiko in 1983, a gift from his wife when he retired from the Navy. Years later, Osborn sold the Doxa and a personal Rolex to a jeweler, saying, “The cash went into my pocket and I never gave it a second thought.” We may not have the watch or its serial number, but this is a second piece of evidence—after the Laffery photo—supporting the issue log we found.

Doxa 6665416 Leo Gies, Lieutenant Commander, USN

While I failed to contact LCDR Gies via email, the salty old Naval officer was kind enough to give me a call one Friday morning. Despite the passing of some five and half decades, Gies is razor sharp and remembered being issued a Rolex dive watch before receiving the Doxa when he joined the SEALAB III program. Sadly, the Doxa is no longer in his possession. After leaving the Doxa with a watchmaker in the 1970s, Mr. Gies explained he never saw it again, thinking it was perhaps sold under dubious circumstances. It’s the kind of thing that could break a watch enthusiast’s heart, but for Gies, another lost diving tool wasn’t a huge deal then or now. In any case, Gies’s recollection serves as another hard firsthand link confirming the US Navy’s issue of Doxa watches during SEALAB III.

Doxa 6665358 Keith H. Moore, Machinist’s Mate Second Class, USN

I met Omar Moore in 2022 at a SEALAB reunion. He was wearing a Navy-issued Doxa T-graph, the stuff of legend.

The hardest to track down was ironically the only aquanaut from the list I have met in person, Keith “Omar” Moore. On the very trip where I discovered the issue log in question, I also attended 2022’s SEALAB reunion. Moore attended wearing the impeccable example of a Doxa T-Graph photographed above, a watch he says was also issued to him by the Navy in 1968, before its commercial introduction in 1969. Could one of the serial numbers on this list belong to Moore’s T-Graph? After several unanswered emails, I asked a couple of the other aquanauts I connected with to vouch for me to Moore.

It did the trick. One morning a few days later, the phone rang. Moore informed me he was indeed issued a Doxa on one of the days listed in our note. He remembered Bob Barth setting up a small folding table not unlike a bake sale where SEALAB III divers and support staff could go and make an argument for why they should be issued a watch. Moore’s rapport with Barth was good, and Moore distinctly remembered Barth throwing him his brand new Searambler dial Doxa in its box from “across the room”. Where Barth got the watches from is unclear, but it is at least possible Doxa sent the watches to Barth directly or in the care of Barth because of his status as one of the “celebrity” aquanauts along with Mercury 7 astronaut Scott Carpenter.

In any case, a few months later, Barth gave Moore another Doxa, this time the then-pre-production T-Graph chronograph. Moore remembered using both extensively in training dives and while supporting the construction and installation of the SEALAB III at no less than 610 feet of seawater off the coast of California’s San Clemente Island.

“Mr. Moore, can I take a photo of your watch?” “Sure, man, whatever”.

Unfortunately, when I was finally able to confirm the serial numbers of  Moore’s Doxa, both of which he still has, neither matched the handwritten log. Here are the numbers as read (and confirmed) from Moore’s Doxa watches:

Doxa Sub 200 T-Graph - Serial: 6675653

Doxa Sub 300 Searambler - Serial: 717923

How the documented serial numbers manage to differ from Moore’s actual watches is anyone’s guess. Perhaps the recordkeeping on Barth’s part was simply not great—a theory Moore seconded—or the names and numbers had become mixed up as could easily happen with any piece of diving equipment. The idea that the first two numbers of a Doxa serial number indicate the year is also not watertight at this point as we are pretty sure the T-Graph wasn’t around in 1966 when the Doxa Sub itself was in its infancy. There are other examples of vintage T-Graphs with “66” as the beginning of the serial number, so I believe Moore’s example to be correct.

While it isn’t the smoking gun I was hoping for—a perfect match between the serial numbers on the handwritten log and the caseback of a Doxa Sub owned by a surviving Aquanaut—we’ve done more than enough to prove the role played by Doxa during SEALAB III and after, serving as an intriguing addition to the annals of dive and military watch history.

Of course, the mission to record these stories for posterity is never over, so let’s finish with a closer look at the role played potentially by Jaquet Droz during SEALAB III. Though the log lists Moore as the recipient of a “JK Droz”, he has no memory of the watch. The plot thickens…

An Unexpected Contender

Jaquet Droz produced dozens of dive watches during the 1960s and 70s. Could some of them have been used on SEALAB III?

The records indicate that several “JK Droz” watches were also issued alongside the Doxa models. If that sounds familiar, that’s because it sounds like the modern luxury brand “Jaquet Droz” that produces intricate automaton watches. And there is indeed a connection—but let’s get it straight—aquanauts were not wearing complicated watches featuring mechanical butterflies and singing birds worth tens of thousands of dollars during SEALAB III.

Pierre Jaquet-Droz was a prolific watchmaker and automaton producer in the 1700s based in the Swiss city of Neuchatel. His name looms large in the Swiss Jura watchmaking region, and that makes it the perfect borrowed name for a brand—or many. Throughout the years, a few brands have resurrected the Jaquet Droz name to capitalize on his fame and imply a quality product, but many of these have a tenuous connection at best. They all originated in the same area of Switzerland, but that’s about it.

It’s next to impossible to know for sure, but there are a few watch sightings in SEALAB archives that could be Jaquet Droz.

The "JK Droz" watches that were issued have yet to be spotted. They could well be one of the ones pictured above or below, but we have no conclusive evidence. Given the timeframe and the role of the watch, it makes sense that the watch came from Jaquet Droz SA registered by Dr. Charles-Edouard Virchaux in 1964. The name was used to brand watches in the “Coopérative” that he ran. The Coopérative was essentially an OEM manufacturer that produced what were known as “catalog watches” that could be branded by any number of clients.

His in-house brand became known as Jaquet Droz, and they produced watches that looked similar to watches from a number of popular tool watch brands at the time. In the photo above, the “C” case might appear at first glance to be an Aquastar—and it may well be—but indeed Jaquet Droz also produced models resembling this design. Since the logs indicate that a few “JK Droz” watches were issued, this may be one, possibly even a standard skin diver whose bezel fell off. We may never know, but with period ads boasting that there were 1000 distinct models available, the possibility is there.

Jaquet Droz might not get named along with the usual undersea living and exploration watches of the ‘60s and ‘70s, but that’s just it—the story is constantly being written. With these documents, two new brands are imbued with the lore of the United States Navy’s SEALAB program.
