The Omega Seamaster 300 Master brings the broad-arrow hand and spare dial of Omega’s 1957 diver into a thoroughly modern watch. Introduced in 2014, it pairs warm-toned luminous markers with a glossy ceramic bezel—a contrast that gives it more character than a straightforward vintage reproduction.

The steel, black-dial 233.30.41.21.01.001 is the natural starting point; the blue-dial titanium 233.90.41.21.03.001 offers a noticeably lighter feel. Both belong to the earlier Master Co-Axial generation, rather than the redesigned 2021 Master Chronometer line. That distinction matters: the earlier watch has polished bracelet center links and a ceramic bezel, while the later generation uses an aluminum bezel and a different dial layout. The earlier caliber 8400 already provides substantial magnetic resistance, despite lacking the later certification. When handling one, try its independently adjustable hour hand—a genuinely useful feature for travel—and decide whether those bright center links suit your idea of a dive watch.

What owners love

The no-date dial is a big part of why owners keep wearing it: the recessed hour markers give it depth, and the broad-arrow hour hand is easy to pick out at a glance.
On the bracelet versions, the clasp’s push-button adjustment is genuinely useful. You can loosen it as your wrist swells without moving a spring bar or reaching for a tool.

Common Criticisms

The polished centre links on the standard bracelet pick up visible hairline scratches and make the watch look dressier than some owners want. They’re a recurring reason for switching to a strap.
It wears taller than the 41mm diameter might suggest, particularly on the steel versions. Owners who like the restrained dial sometimes find the thickness and weight less restrained on the wrist.
