Omega · Seamaster Diver 300M · 43.5mm · black ceramic · Sedna gold · no date · one left · on Amazon
The Seamaster in black ceramic and gold. No date, one left.
This is the Bond Seamaster made in ceramic and trimmed in gold: the Diver 300M at 43.5mm, reference 210.62.44.20.01.001, a case in black ceramic with an 18k Sedna gold bezel rim, crown and helium valve, a black ceramic bezel ring, a black ceramic dial with laser-engraved waves, Sedna gold markers and hands and no date window, on a black rubber strap with a ceramic pin buckle. Inside is Omega’s co-axial calibre 8806, a Master Chronometer automatic without a date and about 55 hours of reserve; 300 metres, 14.47mm thick, about 120 grams. One left, under Omega’s own price when read, from a marketplace seller on Amazon; the seller’s 100-metre row is wrong.

Ceramic, gold, and no date
The 2018 Seamaster Diver 300M is the one with the laser-engraved wave dial and the ceramic bezel; this reference takes the case itself to black ceramic, grows it to 43.5mm, and puts the bezel rim, crown and helium valve in Sedna gold, Omega’s rose-gold alloy. The dial drops the date, which is why the calibre is the 8806 rather than the 8800: same Master Chronometer movement, no date wheel, and a cleaner dial with gold markers on black. At about 120 grams on rubber it is light for its size.
The helium valve at ten is the real screw-in valve of the Diver 300M, in gold here. The seller has one unit and lists the same reference a second time at a higher price without a photograph; this page links the one with the photograph. The rows say 100 metres, which is a data-entry error; Omega and the dial say 300.
Reading the listing
The listing carries the reference 210.62.44.20.01.001 in the title and model row and calls it a 43mm Master Chronometer automatic in a ceramic case on a rubber band; its 100-metre row is wrong. The photograph shows the black ceramic case, the gold bezel rim, crown and valve, the black wave dial with gold markers and no date, and the rubber strap. The thickness, lug width, lug to lug, weight, calibre, certification, reserve and 300 metres are Omega’s published figures for the reference.
The seller is MS-TR JAPAN, a marketplace seller, and the rows we read do not state whether the watch is new with Omega’s five-year warranty; ask, and ask for the box and card. Nothing here was measured on the watch.
Buying it on Amazon
This is a regular Amazon listing from a marketplace seller with Amazon’s 30-day return window; it is not a Luxury Stores pre-owned unit and the seller has not published a condition. The second button opens the live search for Seamaster Diver 300Ms in case this one has sold.
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.
