Almost six decades following the debut of its initial SUB 300 model in 1967, Doxa is reintroducing Grade 5 titanium to its core collection. This expansion follows the brand's August 2026 tribute to explorer Clive Cussler's 95th birthday with a unique SUB 300 Ti5 special edition, which already featured a Grade 5 titanium case, a distinct two-layer dial, and a COSC-certified movement. The latest series broadens this titanium range to encompass six new versions, presented in Doxa's signature vibrant palette: the classic Doxa Orange Professional, the sleek black Sharkhunter, the deep blue Caribbean, the striking cherry red Red Coral, and two variations of the luminous Whitepearl. The Grade 5 titanium, utilized for the case, crown, and screw-in case back, offers a significant advantage by being approximately 40 percent lighter than stainless steel, while maintaining superior mechanical strength and resistance to corrosion, making it ideal for both underwater exploration and daily wear. Powering these timepieces is the Swiss automatic Sellita SW200-1 movement, which boasts a frequency of 28,800 vibrations per hour and a power reserve of approximately 38 hours, showcasing hours, minutes, seconds, and the date with certified precision.
These new SUB 300 Ti5 models uphold the foundational characteristics that defined the original 1967 timepiece, featuring an impressive water resistance of 300 meters. They are equipped with Doxa's patented unidirectional rotating bezel, which ingeniously integrates both depth and dive-time scales, a crucial feature designed to assist divers in adhering to the no-decompression limits set by the US Navy. The watch's face is protected by a domed sapphire crystal, enhanced with an anti-reflective coating to ensure optimal visibility. A defining visual element of the SUB 300, the oversized minute hand, is treated with Superluminova for exceptional legibility in varied lighting conditions, and its finish varies between Doxa's iconic orange and classic black, depending on the specific model. The Whitepearl variant stands out as the most visually striking option within this collection. Available with either a black or white Dive Flex rubber strap, its entire dial is coated with Superluminova, offering a radiant glow in low-light environments. During daylight hours, the pristine white dial beautifully contrasts with the titanium case's metallic grey, transforming into a uniformly luminous display when darkness falls.
Each new watch in the series is complemented by a Dive Flex rubber strap, featuring a distinctive woven texture and a secure pin buckle. The Doxa SUB 300 Ti5 collection is now available for purchase through the brand's official website and authorized retailers, with a retail price of $3,190. This collection represents a thoughtful blend of Doxa's rich heritage in dive watch manufacturing with contemporary material science and aesthetic versatility, offering robust, precise, and stylish timepieces for enthusiasts and professionals alike.
