Discover the SUB 300b: Elegance, below sea level and at street level

Stainless steel case, ceramic bezel, sunburst-finish dial with a wave pattern: tool-watch engineering meets urban elegance

The perfect blend of a technical, robust and reliable watch with urban elegance.The diving watch that is equally at ease on a reef, in a boardroom, and any situation in-between.The '?' for ‘BETA’ factor from DOXA: a palette of colors and fresh finishes paired with a subtle bezel redesign for sleekness.

Based on the concept that a sports watch should excel in every scenario, the SUB 300? retains all of its foundational tool watch features while embracing style and elegance. Keeping to the 42.5 mm diameter, DOXA has subtly modified the case design to slim down the profile to just 11.95 mm (compared to the SUB 300T’s 13.65 mm) and reduced the bezel height by 0.5 mm.

The result is a model with lighter, more contemporary proportions: while the stainless steel case maintains the watch’s functional integrity, the black ceramic bezel and a screw-down crown affirm its sport-chic character. The dial’s sophisticated sunburst finish and understated wave motif play with the light, creating a radiant backdrop for the essential information provided by the hands, hour markers and date.

The watch is fitted with an FKM rubber strap in the dial’s color or in white (for the Caribbean and Searambler references). Also available on request is the historic stainless-steel “rice grain” bracelet. Both options come with a deployant clasp featuring a wetsuit extension and the iconic "DOXA Fish" symbol.

Water-resistant to 30 ATM, or approximately 300 meters, the watch is engineered for exploring the seabed in complete safety, its scratch-resistant sapphire crystal is anti-reflective, and the Swiss automatic movement – with DOXA decorations – offers a power reserve of around 38 hours.

True to the DOXA’s ethos of defying convention and always pushing the boundaries, the SUB 300? is a diver that captures the spirit of the times, while cultivating an elegant, modern sport-chic look for the city.
