Bold take: Doxa and Topper have done it again, turning a niche niche into a standout statement. The Full-Lumed Doxa SUB 250T GMT Great White Topper Edition is back, expanding on last year’s buzzed-about SUB 300T Great White by delivering a compact, travel-ready GMT made for ocean lovers and adventurers alike. Limited to 100 pieces, this edition builds on the SUB 250T GMT introduced earlier in 2025, adding a fresh spin on Doxa’s adventure-first design and deep-rooted ties to the sea, with several distinctive details that set it apart.
Inspiration for the watch continues to draw from Northern California’s Farallon Islands and their Great White sharks. The color scheme—clean white dial with navy-blue accents—evokes both the apex predator and the dark Pacific waters, while a portion of proceeds supports marine conservation through the Greater Farallones Association. It’s a product that blends sportiness with purpose.
Design and case details stay true to Doxa’s recognizable ethos. The 40mm stainless steel case preserves the iconic cushion shape, finished with brushing and a flat sapphire crystal. The unidirectional steel bezel carries dual scales for elapsed time and no-deco dives, both filled in navy lacquer to recall Doxa’s rugged diving roots. The crown is screw-down and the caseback is solid and engraved with artwork depicting the San Francisco Bay and Farallon Islands, reinforcing the regional homage. Water resistance is rated at 250 meters.
A standout feature that shifts this edition from day to night is the dial, which is fully luminous using Super-LumiNova BGW9. In darkness, it glows a vivid blue, with blue lacquered hands and applied markers providing contrast against the luminous backdrop. The absence of a date window keeps the dial perfectly symmetrical. A 24-hour GMT hand is included, enabling tracking of a second time zone. Power comes from an automatic Sellita SW330-2 Elaboré grade movement with caller-style GMT functionality and a 50-hour power reserve.
The watch is paired with Doxa’s stainless steel Beads-of-Rice bracelet, featuring a folding clasp and wetsuit extension, and it ships with an additional integrated navy blue FKM rubber strap with a matching clasp. This is a strictly limited edition, with only 100 units, and it carries a price of USD 2,990. Availability is exclusively through Topper Jewelers.
