For sale is an Omega Seamaster Diver 300M “Professional,” reference 212.30.41.20.03.001, the blue‑dial, ceramic‑bezel Co‑Axial generation of the classic Seamaster 300M. This example is in fair used condition with visible wear on the bezel and case, and it comes with the box and cards; however, the warranty card has not been properly stamped and is therefore likely not valid for Omega factory warranty.

Detailed Description
This reference is part of the ceramic‑bezel Co‑Axial update to the classic Seamaster 300M, pairing a 41 mm steel case and helium escape valve with a blue ceramic bezel and matching blue wave‑pattern dial. The ceramic insert offers improved scratch resistance over older aluminum bezels, while the sculpted case and 300 m rating keep the watch firmly in the professional‑dive category.
The blue dial features laser‑etched waves, applied hour markers, and the trademark skeletonized hands, all filled with luminous material for strong low‑light performance. A date window at 3 o’clock adds everyday practicality, and the AR‑treated sapphire crystal helps keep the dial legible in bright conditions. Powering the watch is the Co‑Axial calibre 2500, offering around 48 hours of power reserve and Omega’s Co‑Axial escapement for improved long‑term performance compared to traditional lever movements.
Condition and Set
This Seamaster Diver 300M is in fair condition:
The ceramic bezel shows a few visible marks/wear points.
The case has noticeable scratches and contact marks consistent with regular wear.
The crystal and dial are described as clean overall, with no major defects noted.
It is supplied with:
Important note on warranty: because the warranty card has not been properly stamped or completed by an authorized Omega retailer, it should be treated as likely not valid for Omega factory warranty coverage. It still provides some documentation value but should not be relied upon for official service claims.
For a buyer looking for a modern, blue‑ceramic‑bezel Seamaster 300M as a more affordable daily diver—with box and cards but no effective factory warranty—this fair‑condition example delivers the full SMP look and spec sheet at a value‑oriented entry point.
