Seamaster Diver 300M Co-Axial 41 212.30.41.20 Reference 212.30.41.20.01.003

Seamaster Diver 300M Co-Axial 41 Stainless Steel / Black / Bracelet / Ceramic

Omega sold this steel Seamaster Diver 300M until the 2018 redesign replaced it. It runs on the calibre 2500, an ETA-based movement that Omega fitted with its co-axial escapement, where the current watch has the in-house Master Chronometer calibre 8800.

The ceramic versions pair a polished ceramic bezel with a plain lacquered dial in black or blue. Earlier Diver 300M dials carried a wave pattern, and the waves only came back, laser-engraved, with the redesign. The date sits at three, and the back is solid: Omega only gave the Diver 300M a sapphire back with the 2018 watch.

The case is a millimetre narrower than the current one and a little lower, so on a smaller wrist this is the Diver 300M that sits closer to the arm.
