utting out of this gulf are the Farallon Islands – a series of rocky sea stacks and islands shrouded in mystery and maritime lore, which are just barely visible from the westward-facing San Francisco shoreline. Nicknamed “the Devil’s Teeth,” these islands are teeming with birds, marine mammals, and a thriving population of Great White Sharks.

Now, with its multi timezone tracking, this adventure-ready Doxa SUB 250T GMT pays tribute to those who endeavour to explore such far-flung shores, while its white and blue livery continues the traditions of past Topper Editions, evoking the dark navy blue of the Pacific and the white of the apex predators which call these waters home. New to this Great White edition, is a custom engraving on the caseback which depicts the San Francisco Bay Area, relative to the Gulf of the Farallones. However, just like its 2024 predecessor, the high-contrast dial of this SUB is once again fully luminous, glowing bright blue in low light.

This ‘Great White’ Topper Edition is built around the Doxa SUB 250T GMT platform introduced at Geneva Watch Week 2025. Compact and highly capable, this new 40mm SUB is powered by a Swiss-made automatic movement which retains the ability to track two time zones simultaneously. In keeping with the 2024 Great White design language, this Limited Edition is once again presented as a no-date execution to preserve the SUB’s unique dial asymmetry and maximize its luminous signature in the dark.

Also present is Doxa’s signature unidirectional rotating bezel, with its deep sawtooth edges and dual engravings, enabling a diver to calculate both elapsed dive time and “no-stop” decompression dive times in accordance with US Navy diving tables. These engravings are finished in navy blue lacquer to match the hour markers on the dial. The watch is finished with an AR-coated, flat sapphire crystal, in homage to Doxa’s 1968 original.

Once again, Topper will donate a portion of the proceeds of this Doxa SUB to the Greater Farallons Association, a nonprofit organization which aims to continue critical work restoring and enhancing coastal habitats while protecting marine life in Greater Farallones National Marine Sanctuary, an area of 3,295 square miles off the northern and central California coast.

The waters within Greater Farallones National Marine Sanctuary are a nationally significant marine ecosystem, and one of the most diverse and bountiful marine environments in the world which supports an abundance of life above and below the ocean’s surface, including many threatened and endangered species.

This SUB 250T GMT ‘Great White’ Topper Edition will be supplied on Doxa’s iconic ‘beads of rice’ stainless steel bracelet, which is fitted with a foldout extension, making it suitable for easy fitment over a wetsuit. Included in the special box set will be an additional integrated navy blue FKM rubber strap on Doxa’s stainless steel folding clasp.
