Quick TakeWhat you get here isn't just another dive watch ticking off specs; it's a proper globetrotting companion that happens to be seriously tough underwater. The SUB 250T GMT Searambler feels perfectly sized at 40mm, hitting that sweet spot between vintage cool and modern presence. Forget chunky dive behemoths; this wears comfortably whether you're catching flights or exploring reefs. That Swiss automatic heart inside hums along reliably with a solid 50-hour power reserve, meaning it's ready when you are, no batteries required. Having that skeletonized GMT hand sweeping around adds a layer of functional complexity without cluttering the classic Searambler dial – perfect for keeping track of home time while you're off chasing adventures elsewhere. With 250 meters of water resistance and that indispensable unidirectional bezel (marked in feet, a nod to its roots), it’s genuinely capable beneath the waves. Plus, choosing between the slick 'beads of rice' bracelet or the practical FKM rubber strap, both with that neat wetsuit extension, means it adapts effortlessly from deep dives to dinner dates. It’s a blend of serious tool-watch credentials and undeniable style.

DescriptionThe functional architecture of the Doxa SUB 250T GMT Searambler, reference 855.10.021.10, is engineered around a robust stainless steel case structure. Dimensional specifications measure 40.00 mm in diameter across the primary axis and 42.90 mm lug-to-lug, ensuring a contained but noticeable wrist presence. Vertical dimension, or height, is recorded at 10.85 mm, contributing to its wearability under various attire, including diving suits facilitated by the bracelet extension. Case integrity under pressure is paramount, achieved through a screw-down case back constructed from stainless steel and a screw-down crown mechanism. These elements contribute significantly to the stated water resistance rating of 25 atmospheres, equivalent to 250 meters or 820 feet, suitable for professional diving applications. Protection for the dial is provided by a scratch-resistant sapphire crystal, treated with an anti-reflective coating to maximize legibility by minimizing glare under diverse lighting conditions, from direct sunlight to underwater environments. A key functional component for diving is the unidirectional rotating bezel, calibrated in feet, allowing for the safe measurement of elapsed bottom time. The bezel's unidirectional rotation prevents accidental adjustments that could overestimate remaining dive time, adhering to safety standards for underwater timing devices. Material selection emphasizes durability and corrosion resistance, consistent with marine environment usage.

Internal mechanics rely on a Swiss origin, self-winding automatic movement. This calibre operates at a frequency of 28,800 vibrations per hour (4.0 Hz), a rate conducive to maintaining accuracy and smooth sweep of the seconds hand. Autonomy from winding is provided by a power reserve capacity of approximately 50 hours when fully wound. As specified, the movement features decoration applied by DOXA, indicating attention to aesthetic detail alongside mechanical performance. Time indication includes central hours, minutes, and seconds hands. A date complication is present, typically displayed through an aperture on the dial. Crucially, this model incorporates a GMT function, manifested through a dedicated 24-hour hand, allowing the simultaneous tracking of a second time zone. This skeletonized GMT hand enhances functionality for travelers or individuals coordinating across different geographical locations without obscuring other dial elements. Attachment to the wrist is offered via two distinct options: a stainless steel bracelet featuring the "Beads of Rice" design, known for its comfort and articulation, or an FKM rubber strap selected for its flexibility, durability, and resistance to environmental factors like saltwater and UV radiation. Both the bracelet and strap are equipped with a folding clasp incorporating a ratcheting wetsuit extension mechanism, permitting easy adjustment over dive gear. The interface between the case and strap/bracelet is standardized at a lug width of 18.00 mm. The timepiece features the iconic Searambler dial configuration.
