What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Citizen Promaster Professional Diver

The Citizen Promaster Professional Diver is a serious instrument with a robust technical appearance, featuring strong lines and an aggressive bezel. It utilizes Citizen's Duratect MRK and DLC coatings for scratch resistance. The BN1024-01E model offers a 300m depth rating and a sapphire crystal, with a 365-day power reserve from its Eco-Drive quartz movement. However, its large size, measuring 52.5mm in diameter and nearly 22mm thick, makes it unsuitable for everyday wear. One reviewer notes the absence of an orange minute hand, which is considered effective on other Promaster models. On balance, the Citizen Promaster Professional Diver is a highly capable, albeit massive, dive tool, with its scratch resistance and long power reserve being key strengths.

Fortis Marinemaster M-40

Owners praise the Fortis Amber Orange for its gorgeous appearance and strong wrist presence, noting its crazy lume and 70-hour power reserve. The Doxa SUB 300T, described as having a superb, eccentric design with a highly legible dial and functional no-decompression bezel, uses an ETA 2824-2 movement. However, the SUB 300T's 42.5mm case wears large and its 14mm thickness is not ideal for dress shirts, though it boasts 1,200m water resistance. On balance, owners appreciate the Fortis Amber Orange for its striking aesthetics and impressive lume.
