Doxa expands its renowned Sub 300 lineup with the debut of the Sub 300 Ti5, bringing Grade 5 titanium permanently into the collection. This release features the iconic dive watch in five vibrant color variations, notably including a Whitepearl dial that glows entirely in the dark. The Sub 300 Ti5 maintains the distinctive design elements that have defined the series since its inception in 1967, offering both modern aesthetics and enhanced durability. This introduction caters to enthusiasts seeking a lighter yet robust option for both underwater adventures and daily wear.
The integration of Grade 5 titanium represents a significant upgrade, offering superior strength and corrosion resistance compared to traditional steel, while reducing the watch's overall weight by approximately 40%. This choice of material builds upon previous successful experiments seen in limited editions such as the Sub 300 Carbon Whitepearl and the Clive Cussler edition. The Sub 300 Ti5 retains its 42.5mm x 45mm case with a slim 13.4mm thickness and standard 20mm lug spacing. The case, crown, and screw-in case back are all crafted from Grade 5 titanium, featuring a blend of polished and brushed finishes consistent with Doxa's aesthetic. A patented unidirectional bezel, which allows divers to synchronize depth and dive time, continues to be a central feature. The dial displays hours, minutes, seconds, and date, with an enlarged minute hand for optimal legibility, all protected by a domed sapphire crystal with anti-reflective coating.
Each Sub 300 Ti5 timepiece is powered by a COSC-certified Sellita SW200-1 automatic movement. This ensures precise timekeeping, having undergone rigorous testing across various positions and temperatures. The movement operates at a frequency of 28,800 vibrations per hour, contains 26 jewels, and provides a power reserve of approximately 38 hours. This commitment to certified accuracy underscores Doxa's dedication to quality and performance.
The collection offers five distinct colorways: the classic orange Professional, stealthy black Sharkhunter, deep blue Caribbean, vivid cherry Red Coral, and the striking fully luminous Whitepearl. All models come with a Dive Flex rubber strap that either matches the dial color or is available in black for the Whitepearl variant, featuring a woven texture and titanium pin buckle that evokes the vintage charm of Tropic straps. The Whitepearl model is particularly noteworthy for its full Super-LumiNova dial, providing unparalleled visibility in low-light conditions, while other versions apply the luminous material to the hands and dive indicators.
This new collection is not a limited release but a permanent addition to Doxa's offerings, available through their official website and authorized dealers starting September 2nd, 2026, at a price of €2,990. The decision to make these titanium models a regular part of the collection reflects Doxa's responsiveness to consumer demand and its ongoing evolution in dive watch technology.
