Quick TakeSlipping on the SUB 300 Whitepearl feels like strapping on a piece of diving history, reimagined for today. That crisp white dial just pops against the brushed steel cushion case, giving it a look that’s clean and almost starkly modern, yet undeniably DOXA. Forget flashy; this is about pure function wrapped in legendary design. Underneath that domed sapphire crystal beats a COSC certified heart, a reliable Swiss automatic ready for whatever you throw at it, whether that's exploring reefs or navigating the urban jungle. The patented bezel isn't just for looks; it's a real tool, a nod to the serious divers who relied on the original SUBs. You can feel the quality in the solid steel construction and the satisfying click of the bezel. Choosing between the classic 'beads of rice' bracelet or the matching white rubber strap lets you tune its personality, but either way, it screams robust capability with a distinctly bright attitude. It’s a legend reborn, ready for new adventures.

DescriptionThe timepiece identified by SKU 821.10.011.23, the SUB 300 Whitepearl, utilizes a Swiss origin mechanical movement characterized by automatic self winding capabilities. This calibre has successfully undergone the rigorous testing protocols necessary for COSC Certified Chronometer status, ensuring adherence to stringent standards for precision and reliability across various conditions. Operational power reserve is specified at 38 hours when fully wound. The oscillator operates at a frequency of 28,800 vibrations per hour, equivalent to 4.0 Hertz. Further distinguishing the movement, it features decoration applied by DOXA. Timekeeping indications encompass hours, minutes, and central seconds, supplemented by a date display function positioned at the 3 o'clock location on the dial interface. Case construction employs high grade 316L stainless steel for durability and corrosion resistance. Geometric specifications measure 42.50 mm in diameter, extending to 45.00 mm lug to lug, with a total case height profile of 13.40 mm. To ensure water integrity, the design incorporates a screw down crown mechanism and a solid stainless steel screw down case back. Water resistance is certified to 30 atmospheres (ATM), corresponding to a depth rating of 300 meters or approximately 984 feet, suitable for professional diving applications.

Protecting the dial is a scratch resistant sapphire crystal, engineered with a domed profile reminiscent of the original 1967 model's plexiglass, and treated with an anti reflective coating to enhance legibility under various lighting conditions. A signature element is the unidirectional rotating bezel, manufactured according to a Doxa patent. This bezel incorporates a dual scale calibrated in meters, facilitating the calculation of dive time and depth for managing no stop decompression dives. All essential dive related markings on the dial and bezel are treated with Super LumiNova luminescent material, providing clear visibility in low light or underwater environments. The model is presented with attachment options including a stainless steel 'Beads of Rice' style bracelet or an FKM rubber strap coordinated with the dial color. Both options feature a folding clasp mechanism incorporating a wetsuit extension; the rubber strap variant includes a ratcheting adjustment for precise fitting over dive gear. The interface point between the case and strap/bracelet corresponds to a lug width measurement of 20.00 mm. The dial itself is presented in the Whitepearl colorway, maintaining the iconic SUB 300 layout.
