Sub 300ß Searambler

Based on the concept that a sports watch should excel in every scenario, the SUB 300β 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 a historic stainless-steel “rice grain” bracelet and  comes 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 300β is a diver that captures the spirit of the times, while cultivating an elegant, modern sport-chic look for the city.
