Quick TakeOkay, let's talk about the SUB 250T GMT Professional – this isn't just another desk diver trying to look tough. It's the real deal, packing serious dive watch credentials into a super wearable 40mm case that feels just right. DOXA brought back the GMT, and they did it properly, blending that globe-trotting ability with the kind of underwater readiness (250 meters!) that made the brand legendary. Inside beats a reliable Swiss automatic heart, keeping time precisely whether you're crossing time zones or checking your decompression stops (thanks to that classic uni-directional bezel marked in feet, no less). The skeletonized GMT hand is a slick touch, letting you track home time without cluttering that iconic orange dial. Plus, you get the choice between the legendary "beads of rice" bracelet or a killer FKM rubber strap, both with that essential diver's extension clasp. It's a tool watch that cleans up nicely, ready for adventure anywhere, anytime.

DescriptionThis timepiece, designated SKU 855.10.351.21, incorporates a Swiss-engineered mechanical automatic movement known for its self-winding capability. Operational integrity is maintained by a frequency of 28,800 vibrations per hour (4.0 Hz), contributing to the precision of its timekeeping functions. The movement, which features custom decoration by DOXA, offers a substantial power reserve of 50 hours, ensuring continuous operation for over two days without winding or wear. Housed within a robust stainless steel case, the dimensions are meticulously calibrated: a diameter measuring 40.00 mm and a lug-to-lug distance of 42.90 mm, paired with a profile height of 10.85 mm. These proportions aim to deliver a balanced presence on the wrist suitable for diverse wearers. Protection against water ingress is rated at 25 ATM, equivalent to 250 meters or 820 feet, facilitated by a screw-down crown mechanism and a solid stainless steel screw-down case back. These features underscore its suitability for professional diving applications and demanding aquatic environments.

Further technical attributes enhance the watch's functionality and durability. Time indication includes central hours, minutes, and seconds hands. A date aperture provides calendar information. Unique to this model is the GMT complication, indicated by a distinct, skeletonized 24-hour hand, allowing the wearer to track a second time zone concurrently – a vital function for global travelers and professionals operating across different regions. The dial is shielded by a scratch-resistant sapphire crystal, treated with an anti-reflective coating to maximize legibility under various lighting conditions, including direct sunlight and underwater. Surrounding the crystal is a unidirectional rotating bezel, calibrated in feet, a standard safety feature for dive timing that prevents accidental underestimation of immersion time. The watch is offered with two distinct attachment options: a stainless steel "Beads of Rice" bracelet or a color-matched FKM rubber strap. Both options feature a folding clasp equipped with a ratcheting wetsuit extension, allowing for easy adjustment over diving gear. The lug width specification is 18.00 mm, defining the interface point for strap or bracelet changes. The overall design adheres to the iconic Doxa dial layout, prioritizing clarity and functional aesthetics.
