Quick TakeForget stuffy boardrooms; the SUB 250T GMT Sea Emerald is pure adventure distilled into a perfectly sized 40mm package. That deep green dial isn't just color, it's a promise of kelp forests and far-off shores. DOXA nailed the blend here – serious dive watch credentials like the 250-meter water resistance and the solid unidirectional bezel meet the globetrotter's essential GMT complication. The skeletonized 24-hour hand is a neat touch, keeping track of home time without cluttering the iconic dial layout. Underneath, the Swiss automatic heart beats reliably at 4 Hz, storing 50 hours of power – enough to get you through extended travel or a long weekend off-grid. Whether you choose the vintage cool of the 'Beads of Rice' bracelet or the rugged practicality of the FKM rubber, both hug the wrist securely thanks to that handy wetsuit extension clasp. It feels tough, looks sharp, and is ready for wherever your next dive or flight takes you. This isn't just a watch; it's a capable companion built for motion, above or below the waves.

DescriptionThe SUB 250T GMT utilizes a Swiss origin, self-winding mechanical movement engineered for precision and endurance. Operating at a frequency of 28,800 vibrations per hour (4.0 Hz), this caliber provides a power reserve extending to 50 hours following a full wind. Doxa applies specific decoration to the movement, viewable presumably through service or documentation as the case back is solid stainless steel and specified as screw-down. Functional indications provided include hours, minutes, central seconds, and a date display. Crucially for its designation, it incorporates a dedicated 24-hour hand facilitating the tracking of a second time zone, a feature enhancing its utility for individuals crossing geographical time boundaries or coordinating international activities. Legibility is maintained under diverse lighting scenarios via the application of luminous material, complementing the distinctive Sea Emerald dial coloration.

Construction parameters define the watch's physical characteristics and environmental resistance. The case is fabricated from stainless steel, presenting dimensions of 40.00 mm in diameter across the bezel, 42.90 mm lug-to-lug, and a vertical profile height of 10.85 mm. Water integrity is rated at 25 ATM, equivalent to 250 meters or 820 feet, ensured by features including a screw-down winding crown and the aforementioned screw-down case back. Protecting the dial is a sapphire crystal, selected for its high scratch resistance, further treated with an anti-reflective coating to minimize glare. A unidirectional rotating bezel, calibrated in feet for dive timing, is integrated into the case architecture. Attachment to the wrist is achieved via either a stainless steel "Beads of Rice" style bracelet or an FKM rubber strap, both options sharing an 18.00 mm lug width and equipped with a folding clasp incorporating a practical ratcheting wetsuit extension mechanism for adjustability over dive gear.
