Discover a Stunning Dive Watch That Blends Precision with Preservation—And It’s Limited to Just 100 Pieces! The Doxa SUB 250T GMT Great White Topper Edition is more than just a timepiece; it’s a tribute to the majestic and often misunderstood white sharks of Northern California's Gulf of the Farallones. Born from a successful collaboration between Doxa, renowned for its rich history in professional diving watches, and Topper Jewelers, this special edition elevates the brand’s adventurous spirit with direct support for marine conservation initiatives.
Building upon the popularity of last year’s dazzling SUB 300T Great White, which captivated enthusiasts worldwide, the 2025 release pays homage to one of nature’s most iconic predators—symbolized through a striking white-and-blue color palette reminiscent of the sleek white shark and the dark depths of the Pacific Ocean. A part of each sale goes to the Greater Farallones Association, reinforcing the watch’s commitment to protecting marine life along California’s rugged coast.
The watch boasts a compact 40mm stainless steel case, maintaining Doxa’s signature cushion shape, with brushed finishes that add to its rugged appeal and a flat sapphire crystal that resists glare. The unidirectional bezel, engraved with elapsed-time and ‘no-deco’ dive scales filled in navy blue lacquer, is a nod to Doxa’s heritage of crafting practical yet durable dive instruments. The regionally inspired caseback illustrates the San Francisco Bay and the Farallon Islands, further emphasizing the watch’s deep ocean roots. Its impressive water resistance reaches 250 meters, making it perfect for serious divers.
But here’s where it gets truly captivating—by day and night, the dial is fully luminous, coated with Super-LumiNova BGW9 that glows a vibrant blue in the dark. Blue lacquered hands and applied markers set against this luminous background create a visually stunning contrast, ensuring readability in low light conditions. The absence of a date window allows for a perfectly symmetrical dial design, while a 24-hour GMT hand adds the functionality of tracking a second time zone—ideal for travelers or those with international connections.
Powering this beast is the Sellita SW330-2 Elaboré grade automatic movement, which offers caller-style GMT functionality and boasts a generous 50-hour power reserve. This means you can wear it daily without worry about winding or battery changes.
The watch is housed on a stainless steel Beads-of-Rice bracelet featuring a folding clasp and wetsuit extension, perfect for diving or everyday wear. For additional versatility, an extra navy blue FKM rubber strap with a matching clasp is included. Priced at USD 2,990, this exclusive edition is limited to only 100 units, each individually numbered and available solely through Topper Jewelers.
