Doxa has expanded its core SUB 300 collection with the new SUB 300 Ti5, featuring a Grade 5 titanium case. This non-limited range offers five dial colors, including a fully luminous Whitepearl option, and builds upon the success of the earlier limited edition Clive Cussler model. The titanium construction aims to provide a lighter and more durable dive watch experience while retaining the iconic SUB 300 design elements.

The Grade 5 titanium construction offers increased strength and scratch resistance compared to Grade 2 titanium, allowing for finishes like polishing.
The polished outer ring and toothed grip of the bezel contrast with the brushed case body, with the polish achieving a 'black polish' effect due to reflections.
The Whitepearl edition is the only full lume display in the series.
The Red Coral color is a new introduction for 2026.
The dimensions are identical to the standard steel Sub 300, measuring 42.5mm across, 13.4mm thick, and 45mm lug-to-lug.
The bezel's outer ring uses feet rather than meters, aligning with the 50th-anniversary launch of the Sub 300.
The watch is available only on a pin-buckle, color-matched, tropic-style strap.
The use of Grade 5 titanium makes the watch approximately 40% lighter than its stainless steel counterpart.
