Sub 300T

The DOXA Sub 300T is a cornerstone of dive watch history, originally introduced in the late 1960s as one of the first purpose-built professional divers. Its unmistakable cushion case, signature orange dial, and patented no-decompression bezel quickly made it a favorite among both commercial divers and collectors seeking vintage tool watches with real pedigree. Today’s Sub 300T models continue that legacy, blending the vintage aesthetic with modern reliability and build quality.

Current Sub 300T references offer a 42.5mm stainless steel case, 1200m water resistance, and a COSC-certified automatic movement — the ETA 2824-2 in most recent editions. Variants differ mainly by dial color (such as Professional Orange, Sharkhunter Black, and Searambler Silver), bracelet style, and limited edition engravings. Earlier “vintage reissue” 300T models are often confused with the slimmer Sub 300; the 300T is slightly thicker and features the distinctive integrated bracelet endlinks, so clarify exactly which reference you’re after.

Price variation is driven by dial color rarity, limited edition runs, and condition — with original box/papers and unpolished cases commanding a premium. The Sub 300T is not especially prone to aftermarket modifications, but be aware that certain rare dial variants and early reissues can attract collector interest and higher prices. If you’re seeking the classic DOXA diver look with modern specs and everyday wearability, the Sub 300T offers one of the most authentic connections to the golden era of dive watches.
