Ben Hodges bought the 2021 Omega Seamaster 300 because it paired the vintage character he wanted with a technical upgrade and design changes that gave the watch more presence on the wrist. He already owned a Tudor Black Bay, so this was an enthusiast’s choice—not a search for his first dive watch.
Why the 2021 Seamaster 300 stood out
Hodges saw the Seamaster 300 as a distinct expression of Omega’s dive-watch history, not as another version of the Seamaster Diver 300M. The line’s origin is the 1957 CK2913; the 2021 model continues the vintage-inspired direction introduced in 2014 while refining its proportions and details. In his words, “The 300 is to the Seamaster, what the Moonwatch is to the Speedmaster.” Fratello Watches, 2021
Design details that made it feel different
The case is 41 mm across, with a 48 mm lug-to-lug length. Hodges says the end links drop away before the lug tips, helping the bracelet follow the wrist rather than extending the watch’s footprint. His assessment is personal, but it explains why the dimensions mattered to him beyond the headline case diameter.
More depth from crystal and dial
He valued the more prominent, boxy sapphire crystal, which makes the watch appear more dimensional and assertive than the preceding generation. A reduced fixed steel ring around the bezel also changes the visual balance. The bezel insert is anodized aluminum, and the dial’s layered construction adds visual depth.

Bracelet adjustment, with a diver’s trade-off
On his watch, the clasp offers 4 mm of tool-less adjustment. Hodges also notes what it does not offer: there is no fold-out diver extension and no adjustment holes in the clasp. That is a practical limitation to weigh if you expect to resize the bracelet over a wetsuit or make larger on-the-fly changes.
The technical upgrade over the 2014 generation
The 2021 Seamaster 300 uses Omega calibre 8912, with a reported 60-hour power reserve, and is Master Chronometer certified. Time and Watches’ 2021 launch coverage reports the reserve and certification. Certification was meaningful to Hodges because the earlier generation’s calibre 8400 had not been submitted for METAS testing fully cased up; the 2021 model’s certification therefore represented a real distinction, not just a refreshed dial or case.

Who this purchase rationale makes sense for
Hodges’s account is most useful if you are choosing a heritage-styled dive watch for its design and ownership appeal rather than buying solely to fill a practical gap. His decision hinged on the Seamaster 300’s vintage lineage, a more dimensional appearance than its predecessor, the certified calibre 8912, and wrist-fit details he appreciated. He summed up the experience simply: “I enjoy wearing and admiring my Omega Seamaster 300.” Fratello Watches, 2021
