A dive icon returns in titanium

In 1967, DOXA launched the revolutionary SUB concept, considered to be the first truly purpose-designed diver’s watch accessible to a broader public. The radical innovations it introduced at the time soon made it the benchmark for professionals, too. Water-resistant to 30 bar, roughly equivalent to a depth of 300 meters, it was the first to feature a unidirectional bezel with a dual scale for depth and dive time to calculate a safe ascent without decompression stops. Most radical of all: its high-contrast dial which greatly improved readability underwater.

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.
This watch is fitted with DOXA's woven-texture Dive Flex rubber strap, finished on a titanium pin buckle.
