Quick TakeGet ready to make waves with the SUB 250T GMT in that eye-popping Aquamarine! This DOXA isn't just playing dress-up; it's a serious tool watch that happens to look incredibly cool. That 40mm size hits the sweet spot – substantial enough for its dive heritage but totally wearable for everyday adventures. Forget just tracking your dive time with that unidirectional bezel (marked in feet, mind you); the skeletonized GMT hand means you can keep tabs on home base while exploring far-flung locales, whether that's another reef or another continent. Ticking inside is a reliable Swiss automatic heart with a solid 50-hour power reserve, humming away at 4 Hz behind that iconic bright blue dial. And don't sweat the bumps or splashes – sapphire crystal and 250 meters of water resistance have you covered. Choose your vibe: the classic cool of the "beads of rice" bracelet or the modern flex of the matching FKM rubber, both with that essential diver's extension clasp. It’s pure DOXA fun meets function.

DescriptionThe timepiece designated SUB 250T GMT, reference 855.10.241.25, incorporates a case fabricated from stainless steel with dimensional parameters specified as 40.00 mm in diameter and 42.90 mm lug-to-lug. Vertical measurement, or height, is recorded at 10.85 mm. Water ingress protection is rated to 25 atmospheres, equivalent to 250 meters or 820 feet, facilitated by a screw-down crown mechanism and a solid stainless steel screw-down case back construction. Operational interface includes a unidirectional rotating bezel calibrated with diving scales marked in feet. Protecting the dial is a sapphire crystal, selected for its high scratch resistance and treated with an anti-reflective coating to enhance legibility under various lighting conditions. Lug width is standardized at 18.00 mm, accommodating specific bracelet or strap attachments.

Internal mechanics are governed by a Swiss origin, self-winding mechanical movement. This automatic caliber operates at a frequency of 28,800 vibrations per hour (4.0 Hz), ensuring standardized precision. It provides a power reserve autonomously generated for approximately 50 hours when fully wound. The manufacturer confirms the movement features decoration executed by DOXA. Timekeeping indications encompass hours, minutes, and central seconds, supplemented by a date display complication. Furthermore, the inclusion of a skeletonized 24-hour hand facilitates the tracking of a secondary time zone, fulfilling the GMT functionality integral to this model. Attachment options provided are a stainless steel "Beads of Rice" style bracelet or an FKM rubber strap, color-matched to the dial. Both options utilize a folding clasp mechanism incorporating a ratcheting wetsuit extension for diver adjustability.
