Old School vs New School: Evolution of the Hook-and-Loop Dive Watch Strap

The hook-and-loop dive watch strap represents a perfect marriage of function and practicality in the world of professional diving equipment. What began as a utilitarian solution for combat divers has evolved into a refined modern accessory that honors its heritage while embracing contemporary materials and craftsmanship.

The Heritage: Tekna Velcro Watch Strap

The Tekna strap was a favorite of US combat divers, renowned for its depth-compensating design and bombproof reliability. Commonly paired with legendary Seiko dive watches like the 6309 and 7548 Quartz models, this strap became iconic in the diving community.

Its thick velcro construction and stainless steel spring-loaded buckle could handle extreme depths while remaining easy to adjust—even with cold, wet hands or over a wetsuit.

The Personal Connection: Citizen Dive Watches

While Seiko dominated the professional diving community with models like the 6309 and Turtle, my journey with dive watches took a different path. Back in the day, I wore a Citizen dive watch paired with that same rugged Tekna strap. That combination served me well, proving that the strap’s versatility extended beyond just Seiko timepieces.

Fast forward to today, and I’m bridging that heritage with modern innovation by pairing my current Citizen dive watch with the Watches of Espionage Glomar Explorer—a contemporary interpretation that captures that old school aesthetic while utilizing modern materials and refined craftsmanship.

The Evolution: Glomar Explorer Hook-and-Loop Strap

Named after the USNS Hughes Glomar Explorer—the deep-sea drillship covertly used by the CIA to recover Soviet submarine K-129 in 1974—the Watches of Espionage Glomar Explorer represents a modern reimagining of the classic dive strap. After six months of development and countless iterations, this premium strap proves that ‘hook-and-loop’ and ‘premium’ need not be mutually exclusive.

The Glomar Explorer uses ultra-thin custom matte weave nylon construction, a custom 316L stainless steel engraved buckle inspired by vintage dive weight belts, and a tightened strap keeper to ensure security. It’s designed as an ‘adventure strap’—built for an active lifestyle where you need confidence that your watch stays firmly on your wrist.

Bridging Generations

What makes this comparison particularly meaningful is how it represents the evolution of a concept rather than its abandonment. The Tekna strap was never about flash—it was about doing a job under extreme conditions. The Glomar Explorer honors that same ethos while acknowledging that modern materials and manufacturing can improve on the original without sacrificing its soul.

By pairing my current Citizen dive watch with the Glomar Explorer, I’m creating a visual and functional link to my past while embracing the refinements of the present.

The old school aesthetic remains—that unmistakable hook-and-loop profile, the quick-adjust functionality, the tool-watch philosophy—but now executed with premium materials, thoughtful details like the engraved buckle inscription, and color options that let you personalize the experience.

Whether you’re a veteran diver who remembers the Tekna days or a new enthusiast discovering the appeal of a well-executed hook-and-loop strap for the first time, the Watches of Espionage Glomar Explorer proves that respecting heritage and pursuing excellence are not mutually exclusive goals. As the buckle reminds us: USE YOUR TOOLS.
