The original Doxa SUB 300T Conquistador, released in 1968, was the first diver’s watch available to the general public that had a built-in helium release valve. The Doxa SUB 300T is a modern version of the Conquistador and remains loyal to the original aesthetic of this iconic timepiece.

The History: The Doxa Watch Company was created by Georges Ducommun in 1889 when Georges was only 21 years old. Working as an apprentice in Switzerland with an established watchmaker since the age of 12, Georges reputation for being highly skilled and innovative grew, leading him to not only start his own factory but eventually win multiple awards at the Worlds Fair in 1905 and 1906 with his anti-magnetic pocket watch designs. His patented 8-Day DOXA Caliber timepieces were used in Bugatti’s racing cars, and quickly led to other automotive brands using his dashboard-mounted clocks, with ships and airplanes following shortly afterward. The SUB collection was created in the late 1960s with Jacques-Yves Cousteau, which introduced groundbreaking innovations that continue to be in use today for military and sports timepieces.

The Watch: The Doxa SUB 300T features a 42.5mm stainless steel case with a sapphire crystal that sits flush with the bezel. Water resistant to 1200 meters, the SUB 300T has a helium release valve built into the case. Powered by an ETA 2824-2 movement, the SUB 300T has a 42-hour power reserve. The stainless steel “beads of rice” style bracelet features brushed blocks and polished beads, with a micro-adjustment diver’s clasp.

The Details: This Doxa SUB 300T is in very good condition. There is minimal wear on the case, lugs, and bracelet, as visible in the photographs.
