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

Doxa and Belmont Watches: A Military-Inspired Collaboration

Doxa has had a busy year in 2026, releasing several notable limited editions, including collaborations with Hodinkee, Clive Cussler, and Topper Jewelers. Now, they team up with San Diego-based Belmont Watches for a new take on the Sub 300 Beta, a watch that draws inspiration from the military history of its home city.

The “Frogger” Design

The Sub 300 Beta “Frogger” is named after the Navy Underwater Demolition Teams, also known as Frogmen, who were once based in San Diego. The watch features a dark green textured dial, bright orange hands (similar to those on the Doxa Army), and applied markers for enhanced legibility. The most striking feature is the fully sandblasted case and bracelet, a first for Doxa, giving the watch a matte, tactical finish. The black-coated bezel and crown are signature elements of the Sub 300 Beta line.

Dimensions and Wearability

The Beta version of the Sub 300 is thinner and more casual than the standard model, measuring 11.95mm thick, 42.5mm in diameter, and 44.5mm lug-to-lug. It retains the iconic case shape, the split no-deco bezel, and offers 300 meters of water resistance. This makes it a versatile tool watch suitable for both diving and everyday wear.

Limited Edition Details

Only 100 units of the “Frogger” will be produced, and it is available on the Belmont Watches website. It comes on a sandblasted beads-of-rice bracelet and includes a green military-style strap with sandblasted hardware. The retail price is ,890.

Buying Tips and Authenticity Notes

Given the limited production run of 100 pieces, this watch is likely to sell out quickly. If you are considering a purchase, verify the authenticity by checking the serial number and the official Doxa and Belmont collaboration markings. Be cautious of resellers asking for premiums above the retail price, as the secondary market may inflate values. For collectors, this piece offers a unique combination of Doxa’s dive heritage and military-inspired design, making it a worthy addition to any collection.
