Quick TakeOkay, let's talk about the DOXA SUB 250T GMT Sea Emerald. This isn't just some desk diver pretending it can handle the pressure. That deep emerald dial practically pulls you into the Mariana Trench, promising adventure below the waves. But wait, there's more! See that extra hand? That's your golden ticket across continents. While you're exploring coral reefs 250 meters down (yes, it can handle that!), you can still keep track of when happy hour starts back home, thanks to the slick GMT function. It's powered by a proper Swiss automatic engine humming away reliably at 4 Hz, meaning it’s as precise timing your decompression stops as it is catching your connecting flight. The 40mm steel case hits that sweet spot – tough enough for anything, comfortable enough for everyday. And whether you rock the classic 'beads of rice' bracelet or the functional FKM rubber strap, both with that essential dive extension, this watch screams capability without being obnoxious about it. It's a globetrotting, deep-diving companion with looks that kill.

DescriptionThe Doxa SUB 250T GMT, reference 855.10.131.26, utilizes a robust stainless steel case construction designed for demanding environments. Case dimensions measure 40.00 mm in diameter and 42.90 mm lug-to-lug, providing a balanced profile suitable for various wrist sizes. The overall case height is maintained at 10.85 mm, contributing to its wearability. Integral to its underwater capability is the screw-down crown mechanism, which, along with a solid stainless steel screw-down case back, ensures structural integrity and protection against water ingress. This construction achieves a water resistance rating of 25 atmospheres, equivalent to 250 meters or 820 feet, rendering the watch suitable for professional diving applications. The unidirectional rotating bezel, a critical safety feature for dive timing, features dive scale markings calibrated in feet. Protecting the dial is a scratch-resistant sapphire crystal, enhanced with an anti-reflective coating applied to minimize glare and optimize readability under diverse lighting conditions, including direct sunlight and underwater environments. The lug width specification is 18.00 mm, dictating the interface point for strap or bracelet attachment.

Powering the timekeeping and auxiliary functions is a Swiss-origin mechanical movement characterized by its automatic, self-winding capability. This movement operates at a frequency of 28,800 vibrations per hour (4.0 Hz), a rate conducive to accuracy and smooth sweep of the seconds hand. It provides a power reserve of approximately 50 hours when fully wound, allowing for extended periods off the wrist without requiring manual winding. The movement features decoration applied by DOXA, indicating attention to aesthetic detail beyond pure functionality. Time indication includes central hours, minutes, and seconds hands. A date complication is present, typically displayed via an aperture on the dial. A key feature is the inclusion of a 24-hour GMT hand, which is skeletonized for differentiation and works in conjunction with the main hour hand to display a second time zone simultaneously. Attachment options cater to different user preferences and applications: a stainless steel bracelet employing the "Beads of Rice" design is available, featuring a folding clasp equipped with a ratcheting wetsuit extension for quick adjustments over dive gear. Alternatively, a color-matched FKM rubber strap is offered, known for its flexibility and resistance to environmental factors, also secured with a folding clasp incorporating the same ratcheting wetsuit extension mechanism. The dial itself is described as the iconic DOXA layout, presented here in the Sea Emerald colorway.
