On my 7.25″ wrist, it’s hard to deny that the SUB 750T could be a better fit for me than a SUB 300. The extra 2.5mm wide and 2mm lug-to-lug over the SUB 300 (which, for years, I’ve been meaning to buy) fills my wrist quite well, and the thickness, only 0.05mm thicker than the Tudor Black Bay 58 that I spent years wearing, means that it looks big without actually being as monstrous as a lot of over-built watches.
While Doxa does a great job of sharing measurement specs, they could do a better job of conveying their movements, at least on their website. The specs are largely there, but the name isn’t, so let’s clarify that. The watch is powered by a Sellita SW300 automatic movement, decorated by the brand (according to the website), but you won’t see that due to the closed caseback (which is engraved). The 56-hour power reserve is decent, and the 4Hz beat rate is fair as well. However, the movement is not certified with any specific accuracy, which is a shame. For $2,230, you can get the same movement in a Formex Reef diver with COSC certification.
