Illustrative render — hero view of the Omega Seamaster Diver 300M Co-Axial 41mm (steel, black dial, ceramic bezel, bracelet)

Omega · Seamaster Diver 300M · 41mm · pre-owned on Amazon

The Seamaster people search for, at the bottom of the page.

Type Omega into Amazon and the first thing it suggests is this watch. This is the Seamaster Diver 300M in its 2012 to 2018 form: 41mm steel, a black ceramic bezel, a black dial with luminous dots and skeleton sword hands, the date at three, the helium valve at ten, on the steel bracelet, with the Co-Axial calibre 2500 inside and 300 metres on the case. Rebag lists it as Very Good with minor scratches, light wear and minor dings on the bracelet, and no box or papers. It is the least expensive watch on this page. Pre-owned through a Luxury Stores reseller.

Which Seamaster this is

Omega has made the Seamaster Diver 300M since 1993 and changed it three times. The photograph shows the middle version: the one from 2012 to 2018 with the ceramic bezel and a plain black dial without the wave pattern, before the 2018 redesign brought the waves back and the calibre 8800. Under the dial is the Co-Axial calibre 2500, Omega’s first production co-axial movement, a chronometer with about 48 hours of reserve. The helium escape valve at ten is the Seamaster signature; the skeleton sword hands and the dot markers are the ones the line has carried since the Bond years.

Rebag does not give the reference. Everything in the photograph matches the 212.30.41.20.01.003, the steel-on-steel black version of that generation, and that is the reference the figures here are drawn from. Ask Rebag to confirm it from the caseback.

Reading the listing

Rebag gives the case at 41mm and 13mm thick, the band at 20mm, a wrist size of about seven inches, steel case and bracelet, a black dial, an automatic movement with date, a diver’s bezel and a screw-down crown, and the condition: Very Good, with minor scratches and light wear on the case and band and minor dings on the band. It comes with no accessories, so no box and no card. The photograph confirms the ceramic bezel, the dial layout and the helium valve.

The calibre, reserve and water resistance here are Omega’s published figures for the generation the photograph matches, not measured on this unit. A watch of this age should have been serviced; ask when it last was.

Buying it pre-owned on Amazon

This unit is sold by Rebag through Amazon Luxury Stores, authenticated by the seller with Amazon’s 30-day return window on top; it is one piece, and when it sells the listing goes away, so the second button opens the live search for Seamaster Diver 300Ms.

Seamaster Diver 300Ms have resold for under new and close to what pre-owned buyers paid, sometimes more, sometimes less; that is a pattern, not a promise, and nothing here is investment advice.
