Unveiling the Doxa SUB 250T GMT Great White: A Luminous Adventure (2026)

Introducing the Doxa SUB 250T GMT Great White Topper Edition—an exquisite timepiece that embodies adventure and oceanic beauty. Following the success of last year’s highly praised collaboration with Topper Jewelers on the SUB 300T Great White, the partnership has unveiled yet another remarkable creation for 2025. This limited edition watch, restricted to just 100 pieces, enhances the compact and travel-friendly design of the SUB 250T GMT, which debuted earlier this year. It showcases a fresh perspective on Doxa's commitment to adventure and its profound connection to marine exploration.

Drawing inspiration from the Great White Sharks found in Northern California's Gulf of the Farallones, this new model serves as a tribute to both exploration and conservation efforts. Its striking white and blue color scheme reflects the majestic predator and the deep blue hues of the Pacific Ocean. A portion of the proceeds from each sale will support the Greater Farallones Association, an organization dedicated to marine conservation along California’s coastline, making this watch not just a beautiful accessory but also a meaningful investment in environmental protection.

The watch features a 40mm case made from stainless steel, maintaining Doxa's iconic cushion shape. With a brushed finish and flat sapphire crystal, it exudes durability and elegance. The unidirectional rotating bezel, crafted from steel and adorned with elapsed-time and "no-deco" dive scales filled with navy blue lacquer, harkens back to the rugged functionality of Doxa’s early dive watches. The solid engraved caseback artistically depicts the San Francisco Bay and the Farallon Islands, reinforcing the regional theme of this exclusive model. Notably, the watch boasts impressive water resistance rated at 250 meters, ensuring it can withstand the rigors of underwater adventures.

What truly sets this edition apart is its fully luminous dial, coated in Super-LumiNova BGW9, which emits a vibrant blue glow in the dark, making it easy to read even in low-light conditions. The blue lacquered hands and applied markers create a striking contrast against the luminescent background. Uniquely, this model shuns the traditional date display, resulting in a perfectly symmetrical design. Additionally, it features a 24-hour GMT hand, allowing wearers to track a second time zone—a valuable feature for travelers. Powering this sophisticated watch is the Sellita SW330-2 Elaboré grade automatic movement, featuring caller-style GMT functionality and an impressive 50-hour power reserve.

The Doxa SUB 250T GMT Great White is completed with a stainless steel Beads-of-Rice bracelet equipped with a folding clasp and wetsuit extension for added comfort and convenience. It also includes an extra integrated navy blue FKM rubber strap with a matching clasp, giving wearers versatile options for different occasions. Priced at USD 2,990, this exclusive timepiece is only available through Topper Jewelers.
