The green Oyster Perpetual 31, without the paperwork.

Rolex put lacquer dials on the Oyster Perpetual in 2020, green among them, and on the 31mm case the green is the one that reads as a colour rather than a trick of the light. The watch under it is the plain OP: smooth bezel, no date, the calibre 2232 with about 55 hours, the Oyster bracelet with the Easylink extension. Rebag has two green OP 31s on this page; this one has no accessories and the lower price, so compare the grades and what each comes with before choosing.

Sized to a 7 inch wrist; ask whether removed links come with it.

Rebag gives the case at 31mm and 11mm high, the band at 16mm, a wrist size of about 7 inches, the band and case as stainless steel, the dial colour as green, an automatic movement with a screw-down crown, no accessories, and the condition as Very Good with minor scratches. It gives no reference. The green lacquer dial and smooth bezel are in the title and the photograph; the 277200 match, calibre 2232, its certification, the reserve and 100 metres are Rolex’s published figures for the reference it appears to be.

Rebag authenticates in-house and is not a Rolex authorised dealer, and Amazon adds its 30-day return window. Ask for the reference and the serial, and when it was last serviced. Nothing here was measured on the watch.

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 31mm Oyster Perpetuals.

Steel Oyster Perpetuals have resold close to what pre-owned buyers paid, sometimes more, sometimes less; that is a pattern, not a promise, and nothing here is investment advice.
