The Full-Lumed Doxa SUB 250T GMT Great White Topper Edition

Following a well-received collaboration between Doxa and Topper Jewelers, last year’s white-hot SUB 300T Great White, the partnership returns for 2025 with another creation: the Doxa SUB 250T GMT Great White Topper Edition. Limited to 100 pieces, this new release builds upon the compact, travel-ready SUB 250T GMT introduced earlier this year, offering a fresh take on the brand’s adventure-driven design and deep connection to the ocean… With a few unique features to make it truly special.

Inspired once again by the Great White Sharks that roam Northern California’s Gulf of the Farallones, the new model pays tribute to exploration and preservation. The white-and-blue colour scheme evokes the apex predator and the dark navy of the Pacific; a portion of proceeds will benefit the Greater Farallones Association, supporting marine conservation along California’s coast.

The 40mm stainless steel case of the SUB 250T GMT Great White Topper retains Doxa’s classic cushion shape, brushed surfaces, and a flat sapphire crystal. The unidirectional steel bezel, engraved with both elapsed-time and “no-deco” dive scales filled in navy blue lacquer, recalls the rugged functionality of Doxa’s early dive watches. The screw-down crown and solid engraved caseback, depicting the San Francisco Bay and Farallon Islands, highlight the edition’s regional inspiration. Water resistance is rated at 250m.

Setting this edition apart day and night, the dial is fully luminous, coated with Super-LumiNova BGW9 and glows a vivid blue in the dark. Blue lacquered hands and applied markers contrast against the dial’s glowing surface, while the unprecedented no-date execution preserves perfect symmetry. The addition of a 24-hour GMT hand allows for tracking of a second time zone. The watch is powered by an automatic Sellita SW330-2 Elaboré grade movement with caller-style GMT functionality and a 50-hour power reserve.

The SUB 250T GMT Great White comes fitted to Doxa’s stainless steel Beads-of-Rice bracelet with folding clasp and wetsuit extension, and includes an additional integrated navy blue FKM rubber strap with matching clasp. The watch is limited to 100 pieces, priced at USD 2,990 and available exclusively from Topper Jewelers.
