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. All models are fitted with woven-texture Dive Flex rubber straps, with strap colors selected to complement each individual dial configuration.
