The SUB 300 Ti5 brings Grade 5 titanium back to DOXA’s permanent collection, combining the iconic SUB 300 architecture with a lighter, stronger and highly corrosion-resistant construction. Measuring 42.50 × 45.00 mm with a thickness of 13.40 mm, the case, screw-down crown and screw-in caseback are crafted from Grade 5 titanium, offering exceptional strength-to-weight ratio and wearing comfort.

Water-resistant to 300 meters (984 feet), the watch retains DOXA’s patented unidirectional rotating bezel with its dual depth-and-dive-time scale, supporting divers within established no-decompression limits. Beneath the domed, anti-reflective “glass box” sapphire crystal, all dive-related indications are coated with Super-LumiNova®, while the signature oversized DOXA orange minute hand provides immediate readability.

The SUB 300 Ti5 is powered by a COSC-certified Swiss automatic movement operating at 28,800 vibrations per hour (4 Hz), with approximately 38 hours of power reserve.
The collection comprises seven expressions, including two Whitepearl references with fully Super-LumiNova®-coated dials that transform into luminous surfaces as light fades. All models are fitted with woven-texture Dive Flex rubber straps, with strap colors selected to complement each individual dial configuration.
