The fourth-generation Seamaster Diver 300M brought the waves back in 2018, this time laser-engraved into ceramic rather than cut into the earlier metal dials. It’s a sharper, more substantial take on the familiar skeleton-hand diver, and those waves give the dial a liveliness that the preceding smooth-dial generation deliberately set aside.

The blue-dial 210.30.42.20.03.001 is the natural starting point if you want the classic Seamaster look; the white-dial 210.30.42.20.04.001 offers stronger contrast with its black bezel and hands. Both use the Master Chronometer 8800, with the date neatly relocated to six o’clock. Try the bracelet and rubber versions if possible: the broad bracelet makes this 42mm case feel more substantial, while rubber changes its character considerably. Pay particular attention to how the protruding helium valve sits against your wrist, and inspect the ceramic bezel’s edge for chips—ceramic resists scratches, but not every impact.

What owners love

The wave dial rewards a second look: the pattern and polished hands change noticeably with the light. Owners also regularly praise the lume, especially how easily the hands stand out in the dark.
The 8800 gets plenty of praise for steady, accurate running in everyday wear. Being able to see the movement through the caseback is a detail owners enjoy rather than just a specification.
The bracelet’s push-button clasp adjustment is genuinely useful when your wrist swells during the day. Owners who prefer the rubber strap often say it makes the watch feel considerably less bulky.

Common Criticisms

The bracelet’s lack of taper is a recurring gripe: it feels broad all the way around the wrist, and the clasp adds noticeable bulk underneath. Some owners like the watch head much more than the bracelet.
The scalloped bezel can be slippery and awkward to turn, particularly with wet fingers. Its shape looks distinctive, but owners often wish it offered a better grip.
The protruding helium valve at 10 o’clock remains divisive. Even owners who love the rest of the watch sometimes find it visually distracting and would rather it weren’t there.
