Pilots in general, whether military or civilian, have one of the strongest watch cultures of any profession, with many opting for mechanical GMTs and chronographs from brands like Rolex, Omega, Breitling, and Seiko. For aviation professionals, the Use Your Tools ethos is alive and well, and pilots are responsible for several of history’s most important watches, from the Rolex GMT-Master to the Breitling Navitimer. In this Dispatch, we’ll explore watch culture among military pilots and aircrew. 

From Waltham To Suunto & Now W.O.E., A Wrist Compass Is Essential Gear For Countless Special Operators While the tools of warfare have developed rapidly over the past sixty years, some gear has remained virtually unchanged, timeless tools that are as effective in 2024 as they were in 1964. Among those essential items are the wristwatch and the wrist compass, both utilized extensively as tools by Intelligence and SpecOps personnel throughout the past six decades.

The archetypal image of the Vietnam-Era SEAL or a MACV-SOG operator almost always includes not only a watch but also a wrist compass, worn on the same strap. Often overshadowed by the watches they accompany, wrist compasses are useful tools favored by divers and special operators, backed by an intriguing history that stretches from the Vietnam War until today.

Submersible Compass. Wrist Compasses & Special Operations - A Brief History While the concept dates back to ancient China, the compass as we know it today started seeing widespread use as a tool by mariners navigating at sea as early as the 1100s. Military organizations began issuing smaller, more portable compasses en masse to ground-based troops as early as the First World War, a conflict that also saw the widespread adoption of wrist-worn as opposed to pocket watches. Modern SpecOps finds its roots in the Second World War. During this period, the nascent Navy Scouts and Raiders from the United States and British Special Air Service (SAS) and Long Range Desert Group (LRDG) commandos utilized lensatic compasses with built-in sighting mechanisms for wayfinding in challenging terrain.

By the early 1950s, dive watches including the Blancpain Fifty Fathoms and Rolex Submariner had already become essential parts of any military diving load out. Like watches, the compass would also need to adapt to fit the needs of an evolving military.

(Photo Credit: US Navy) Underwater compasses had been used by divers for decades by that time but were cumbersome for clandestine maritime operators after leaving the water. In the 1960s, numerous scuba diving brands including Aqualung, Dacor, and Scubapro produced simple oil-filled compasses designed to slide over a watch strap. These diving-specific compasses famously appear in photographs alongside watches like the Rolex Submariner and the Doxa Sub 300/300T during the US Navy’s SEALAB experiments.

Given the sizing norms of watches during the period when many tool watches measured 32 millimeters, the compass came equipped with 16mm canvas and later nylon straps. Designed for use by downed pilots, these compasses, which were initially marked “Waltham” and later “W.C.C.” for Waltham Clock Company, would not see widespread use until the Vietnam War when SEALs brought them into action alongside their issued Tudor 7928s.

Army Special Forces operators assigned to MACV-SOG also selected the brass wrist compass for use alongside their issued Seiko watches. When we interviewed John Stryker Meyer, a legend in the SF community, he said that some of his fellow Recon Company soldiers added a W.C.C. compass to the strap, but he preferred the traditional compass around his neck. For special operations forces, the need for a more portable compass stemmed from the level of autonomy and individual responsibility entrusted to each operator. These Waltham compasses, which are still relatively available through surplus or militaria channels, are becoming increasingly collectible due to their SpecOps associations.

Issued escape and evasion kits still included the Waltham in many cases, but some frogmen of the 1980s opted for diving-specific compasses from brands like Silva and Tekna. The Cammenga J582 (left) and Suunto M-9 (right) are among the most popular wrist compasses among special operators today. Over time, several brands stepped up to produce simpler and cheaper compasses which evolved along with the world of watchmaking. Starting in the 1990s, the NSN or Nato Stock Number formerly held by Waltham was taken over by Stocker & Yale with a modernized version of the W.C.C. with tritium gas tube illumination housed within an aluminum case. In 2004, Cammenga, already a maker of many issued compasses, purchased the rights and continues to manufacture the mil-spec wrist compass, now called the J582, for the US Military. While it is an effective tool, the Cammenga is not designed for extended diving or swimming operations.

For wear on a watch strap, Suunto’s Clipper compass and a similar design from Marathon are also common options for military personnel. All offer significant utility for special operators, but most lack the refinement to go toe to toe with watches from brands like Rolex, Omega, Tudor, and Seiko. The W.O.E. Submersible Wrist Compass A core principle of everything we do at W.O.E. is honoring our heritage. Inspired by the link between tool watches utilized by SpecOps and capable wrist compasses, we set out to design a modern compass measuring that also calls back to the W.C.C. wrist compasses historically used by SpecOps. The result of over two years of prototyping and extensive testing by divers and SpecOps personnel, the W.O.E. Submersible Wrist Compass is a capable tool that celebrates the heritage of our community. With a custom dial featuring C3 Super-LumiNova, a grade two titanium case, individual water resistance testing to 100 meters, and slim 24.5mm wide by 12mm thick dimensions, the W.O.E. Submersible Wrist Compass is a capable tool that also looks the part alongside tool watches from Seiko, Rolex, Omega, and Tudor. Click HERE to learn more about the W.O.E. compass.

The goal was to find a so-called “superclone,” the highest tier of counterfeit watches that claim to mirror genuine models down to the weight, finishing, and movement. According to internet lore, the superclones are so good that even an expert watchmaker can’t distinguish them from the real thing.

Dave Hall is a close friend of W.O.E., the subject of one of our first in-depth profiles, and a rare special operations veteran who appreciates watches as much as any nerd in any room. When we added an interview format to the W.O.E. YouTube Channel, it was only a matter of time before we sat down in Dave’s office, packed with a career’s worth of SEAL keepsakes, to discuss his life in the Teams through his watch collection.
