DOXA SUB 300 Carbon

The DOXA SUB 300 Carbon is widely praised for its exceptionally lightweight forged carbon case, offering superior comfort and a unique texture, with reviewers calling it a "tactical featherweight." Owners and reviewers alike highlight its vintage dive watch aesthetic, vibrant dial options, and satisfyingly clicky bezel. The COSC-certified automatic movement is noted for reliable timekeeping, with accuracy reported between +0.9 and +5 seconds per day. Some sources mention a 38-hour power reserve as a trade-off for its slimness. The integrated rubber strap is generally found comfortable and adjustable, though one reviewer noted sharp edges on the clasp and another that the strap requires cutting to size. The bezel's no-decompression markings are flagged as potentially outdated for modern diving. Overall, owners and reviewers rate the DOXA SUB 300 Carbon highly for its unique lightweight construction and compelling vintage design at the price point.
