Omega · Planet Ocean · 39.5mm · black ceramic · rubber · discontinued · on Amazon
The small Planet Ocean in ceramic. 600 metres at 98 grams.
This is the Planet Ocean at its smallest, in ceramic: the 600M at 39.5mm, reference 215.92.40.20.01.001, a case and bezel in black ceramic, a black dial with Arabic numerals at six, nine and twelve, the date at three, a helium valve, on a black rubber strap with a ceramic foldover clasp. Inside is Omega’s co-axial calibre 8800, a Master Chronometer automatic with about 55 hours of reserve; 600 metres, 14.52mm thick, about 98 grams. Omega lists the reference as no longer available; from a marketplace seller on Amazon, whose 19mm thickness row and steel-bracelet row are wrong.

A 600-metre diver at 39.5mm
Omega made the Planet Ocean in 39.5mm from 2016 as the size for smaller wrists, with the calibre 8800 and the same 600 metres and helium valve as the 43.5; this reference is the version in black ceramic rather than steel, on rubber, which brings it to about 98 grams. The dial has the Planet Ocean’s Arabic numerals at six, nine and twelve and the date at three. Omega has since discontinued the ceramic 39.5, so what the seller has is old stock or a pre-owned unit; the listing does not say which.
It is 14.52mm thick, which is the price of 600 metres in any size; the seller’s row says 19mm, a data-entry error, and its components row says steel bracelet where the photograph and Omega show a rubber strap. The 8800 is Master Chronometer, so METAS has tested it to 15,000 gauss.
Reading the listing
The listing carries the reference 215.92.40.20.01.001 in the title and model row and calls it a 39.5mm Swiss automatic in a ceramic case with 600 metres on a 19mm rubber band; its 19mm thickness row and steel-bracelet components row are wrong. The photograph shows the black ceramic case and bezel, the black dial with Arabic numerals, the date at three and the rubber strap. The thickness, lug width, lug to lug, weight, calibre, certification and reserve 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 Planet Oceans in case this one has sold.
Planet Oceans 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.
