Doxa and Belmont Watches Unveil the Sub 300 Beta “Frogger” Limited Edition

A New Collaboration Rooted in Military History

Doxa continues its impressive run of releases in 2026 with a fresh partnership that draws inspiration from the military heritage of San Diego. The city, home to the Naval Amphibious Base Coronado and SEAL Team 1, was once the headquarters of the Navy Underwater Demolition Team—better known as the Frogmen. This rich history serves as the backdrop for the new Sub 300 Beta “Frogger,” a joint effort between Doxa and Belmont Watches.

Design and Features

The “Frogger” edition is unmistakably tool-oriented, designed with the kind of rugged functionality that would suit a modern-day frogman, whether on a dive or above the surface. The dial is a deep, textured green, complemented by bright orange hands that echo the style found on the Doxa Army. This model also incorporates applied markers for enhanced legibility. Perhaps the most striking feature is the fully sandblasted case and bracelet—a first for Doxa—which gives the watch a matte, stealthy appearance. The black-coated bezel and crown, signature elements of the Sub 300 Beta line, complete the aggressive look.

Wearability and Dimensions

The Sub 300 Beta is known for being a slimmer, more casual interpretation of Doxa's iconic diver. With a height of just 11.95mm, a diameter of 42.5mm, and a lug-to-lug of 44.5mm, it wears more comfortably than the standard Sub 300 while retaining the distinctive case shape and split no-deco bezel. Despite its refined profile, it maintains a full 300 meters of water resistance, ensuring it remains a capable dive tool.

Limited Availability and Pricing

Only 100 examples of the Sub 300 Beta “Frogger” will be produced. At the time of writing, a few units remain available on the Belmont Watches website. The watch comes on the sandblasted beads-of-rice bracelet, with an additional green mil-strap featuring sandblasted hardware. The retail price is set at ,890.

Final Thoughts

The Doxa Sub 300 Beta “Frogger” is a bold, military-inspired addition to Doxa's lineup, offering a unique aesthetic that sets it apart from previous releases. Whether you're a collector of Doxa's limited editions or a fan of rugged, tool watches, this collaboration is worth considering—if you can secure one before they sell out.
