Doxa and Belmont Watches Issue a Military-Inspired Sub 300 Beta Frogger
Doxa and Belmont Watches of San Diego have released a Sub 300 Beta “Frogger” collaboration with a military-inspired brief. According to Hodinkee’s 25 August report, the piece takes the orange-and-tool Doxa language and pulls it toward a service look rather than a leisure dive colourway.
Belmont is a retailer with a collaboration habit. Doxa’s Sub 300 Beta is a known chassis: professional-leaning dive watch, distinctive bezel, a name that already sounds like a nickname. Frogger as a title will do the marketing work. Builders who want a similar tool silhouette on a Seiko donor can start with the Seiko Prospex mod guide rather than chasing orange Doxa parts that will not fit an SKX case.
What a military-inspired Doxa usually changes
Military-inspired dive watches typically mute the orange, add a darker insert, and specify a strap that can be replaced in the field. They do not automatically add a government contract. Hodinkee’s report is the public label for the collab; full water-resistance and movement figures belong on the hang tag.
- Partners: Doxa and Belmont Watches (San Diego)
- Base: Sub 300 Beta
- Name: Frogger
- Brief: military-inspired
- Coverage: Hodinkee, 25 August
Bezel inserts carry most of the “military” signal: matte, high contrast, no tropical orange. Fitment is unforgiving. If you are doing insert work on a different brand, read the bezel insert material and fit guide before you order a 0.1mm-wrong ring.
Retailer collabs and why they stick
A shop in San Diego putting its name on a Swiss dive watch is a small-run story. The watch will be sold to people who already trust Belmont, plus a few Doxa collectors who chase every Beta variant. That is a healthy, limited audience. It is not a global colourway.
Strap choice will split the owners. Rubber is the dive default; a metal bracelet is the desk default. The rubber vs metal bracelet guide covers that split. Jubilee versus oyster-style links is a further fork if a bracelet is offered; see the Jubilee vs Oyster bracelet guide.
If you are building a tool watch instead
A Sub 300 Beta is not an NH35 case. Do not mix parts. If the Frogger look is the inspiration and a 5KX or Prospex is the budget, keep the donor’s gasket stack and change dial, insert and strap only. Compatibility is a list; use the Seiko mod compatibility checklist. After the build, pressure-test before seawater. The water resistance testing guide is the step most forum posts skip.
Lume plots on military-inspired dials are often greener and denser than leisure Doxa orange. Matching hands to dial is a chemistry and height problem; the lume upgrade guide is the reference for Seiko-family plots.
FAQ

The brief is military-inspired rather than a leisure orange colourway. Confirm the actual dial and insert on Belmont’s listing.
