Doxa Sub 300 Ti5 

Born from more than six decades of professional dive watch expertise, DOXA SUB 300 Ti5 watches bring one of Swiss watchmaking’s most distinctive diving designs into a new generation of lightweight performance. Grade 5 titanium transforms the familiar SUB 300 architecture, combining exceptional strength, corrosion resistance and reduced weight with the purposeful character that has defined DOXA dive watches since the 1960s. Measuring 42.5mm × 45mm with a 13.4mm case thickness, the SUB 300 Ti5 retains the unmistakable proportions, curved profile and highly functional layout associated with the collection while introducing a contemporary titanium finish. A unidirectional rotating bezel incorporates DOXA’s signature dual scale for dive time and depth calculations, while the domed glass box sapphire crystal reinforces the characteristic vintage inspired silhouette. Water resistance to 300 metres ensures serious diving capability, complemented by highly visible Super LumiNova details and the oversized minute hand synonymous with DOXA’s underwater instruments. Power comes from a Swiss automatic mechanical movement operating at 28,800 vibrations per hour, with approximately 38 hours of power reserve and COSC Chronometer certification for independently tested precision. Every element combines the heritage of the original SUB 300 with modern materials and engineering, creating a distinctive Grade 5 titanium Swiss dive watch designed for professional capability, collecting and everyday wear.

Colour has always been central to DOXA’s identity, and the SUB 300 Ti5 collection continues that tradition through some of the most recognisable dial executions in modern dive watch design. Iconic Professional orange, Sharkhunter black, Caribbean blue and Redcoral references sit alongside striking Whitepearl interpretations, giving the collection a broad visual character while maintaining the same technical foundation throughout. Each version is fitted to a woven texture Dive Flex rubber strap with a matching Grade 5 titanium pin buckle, extending the lightweight construction beyond the case and creating a comfortable configuration suited to both diving and daily use. Beneath the individual colourways lies a design lineage stretching back to the pioneering DOXA SUB 300 of 1967, a watch created during a defining period in recreational and professional scuba diving. The Ti5 evolves that heritage through advanced titanium construction without disguising the distinctive case shape, bezel architecture and dial legibility that make a DOXA immediately recognisable.
