Quick TakeOkay, let's talk about the Whitepearl. It's got that unmistakable DOXA chunkiness, that tool-watch vibe born in the deep, but with a twist. That crisp white dial – the 'Whitepearl' – just pops. It’s like finding a pristine shell on a rugged seabed. You still get the serious specs: the 1,200 meter water resistance, the helium escape valve for those who actually use it (or just like knowing it’s there), and that iconic no-deco bezel. It’s reassuringly over-engineered. But the white dial shifts the mood. It feels less like a strictly underwater instrument and more like something you'd wear cresting a wave on a sun-drenched speedboat. The contrast between the stark white and the bold black hands/markers is fantastic for legibility, sure, but it's also just cool. It runs on a solid Swiss automatic heart, ticking away reliably, and the 'Beads of Rice' bracelet is pure vintage comfort. It’s a nod to history, built for today, with a face that’s surprisingly bright and optimistic for a watch capable of such serious depths. It’s the tough diver that cleaned up nicely for a party.
DescriptionEngineered from high-grade 316L stainless steel, the casing of the SUB 300T Whitepearl presents dimensions of 42.50 mm in diameter and 44.50 mm lug-to-lug, with a profile height measuring 13.65 mm. This robust housing ensures structural integrity and corrosion resistance, essential for marine environments. Protection for the dial is afforded by a scratch-resistant sapphire crystal, enhanced with an anti-reflective coating to maximize legibility by minimizing glare under various lighting conditions. Integral to its deep-diving capability is the screw-down crown and a solid stainless steel screw-down case back, which contribute significantly to its profound water resistance rating. The watch is certified to withstand hydrostatic pressures equivalent to 120 ATM, translating to a functional depth of 1,200 meters or 3,937 feet. A defining feature is the integrated helium release valve (HRV), a critical component for saturation diving, allowing trapped helium molecules to escape the case during decompression, thereby preventing crystal displacement.
Powering the timekeeping functions is a Swiss mechanical automatic movement, operating on a self-winding mechanism. This caliber vibrates at a frequency of 28,800 vph (4.0 Hz), contributing to the smooth sweep of the seconds hand and maintaining accuracy. The movement provides a power reserve of approximately 38 hours when fully wound, ensuring continuous operation off the wrist for over a day and a half. Decoration of the movement is executed by DOXA, adding a touch of refinement visible should the case back be removed during servicing. Time indication is provided through central hour, minute, and second hands, alongside a date complication displayed through an aperture on the dial. For dive timing, the watch incorporates DOXA's patented unidirectional rotating bezel, calibrated in feet, featuring an integrated no-decompression dive time calculator. Luminescent material, specifically Super-LumiNova®, is applied to all critical dive-related elements on the dial and bezel to ensure optimal readability in low-light underwater conditions. Attachment options include a stainless steel "Beads of Rice" bracelet or an FKM rubber strap, both secured with a folding clasp incorporating a ratcheting wetsuit extension for adjustability over dive gear. The lug width is specified at 20.00 mm.
