Product Details
The SUB 250T GMT marks DOXA’s return to the GMT function, blending dive-watch durability with world-time functionality. Its 40mm stainless steel case ensures a perfect balance of wrist presence and comfort, while the screw-down crown and unidirectional bezel with diving scales provide professional-grade performance. With a water resistance of 250 meters (820 feet), it’s built for both underwater exploration and global travel.
Powering the SUB 250T GMT is a Swiss automatic movement, operating at 28,800 vibrations per hour (4 Hz) with a 50-hour power reserve, ensuring precision and reliability in any environment. The skeletonized GMT hand allows tracking of a second time zone, making it a practical tool for divers and frequent travelers alike. Beneath the scratch-resistant sapphire crystal with anti-reflective coating, the watch maintains excellent legibility in all conditions.
Completing its rugged yet refined design, the SUB 250T GMT is available with either a color-matched FKM rubber strap for superior flexibility and durability or the stainless steel “beads of rice” bracelet, both featuring a folding clasp with a diving suit extension. A seamless blend of heritage, innovation, and adventure-ready performance, the SUB 250T GMT is built for those who demand reliability and style—whether deep underwater or across time zones.
