DOXA SUB 300 Ti5: The classic diver's watch gets lighter

With the SUB 300 Ti5, DOXA has reimagined one of its most iconic diver’s watches in Grade 5 titanium. The material significantly reduces the weight without compromising the SUB 300’s utilitarian character. At launch, the new model will be available in several familiar DOXA colors and will become part of the regular collection.

Grade 5 titanium instead of stainless steel

The case, crown, and back are made of Grade 5 titanium. This makes the watch about 40 percent lighter than one made of stainless steel. At the same time, the alloy allows for precision-machined surfaces and high durability. The SUB 300 Ti5 is water-resistant to 300 meters.

The classic SUB-300 silhouette

The barrel-shaped case, the domed crystal, and the patented unidirectional rotating bezel remain unchanged. The latter combines a time scale with a depth chart and has been one of the brand’s defining features for decades. A flexible rubber strap continues this functional design approach.

Multiple colors, one technical foundation

DOXA offers the titanium version in distinctive color schemes. These include the orange Professional dial, the black Sharkhunter, and the blue Caribbean. There are also other variants, including the Whitepearl, which features a full-surface Super-LumiNova display for exceptionally clear readability in the dark.

COSC-certified automatic movement

Inside, an automatic, COSC-certified movement operates at a frequency of 4 hertz and offers approximately 38 hours of power reserve. The certification underscores that the change in materials is not solely aimed at reducing weight: The SUB 300 Ti5 remains a full-fledged diver’s watch with chronometric precision.

A Lighter Take on a Classic

The SUB 300 Ti5 revamps the familiar design, particularly at the wrist. Titanium noticeably reduces the weight of this robust diver’s watch, while the colors, bezel, and case shape preserve its historic appeal. With this model, DOXA expands the line to include a technically modern, permanently available alternative.
