Is an Omega on Amazon authentic?

Omega · Speedmaster Racing · 40mm · pre-owned on Amazon

The Speedmaster with the column wheel, at 40mm.

The Speedmaster Racing is the Speedmaster that took the modern movement first: in 2012 Omega fitted it with the Co-Axial calibre 3330, a column-wheel chronograph with a silicon balance spring, while the Moonwatch kept its hand-wound calibre. This is the 40mm version: a steel case, black tachymeter bezel, matte black dial with a chequered minute track, two counters, small seconds with the date at six, on the steel bracelet. Rebag lists it as Very Good with minor scratches and light wear, with a dated warranty card, and it is the least expensive Speedmaster on this page. Pre-owned through a Luxury Stores reseller.

Racing, not Moonwatch

Omega makes several Speedmasters and the names matter. The Moonwatch is the hand-wound one with the hesalite crystal, unchanged in spirit since 1969. The Racing is its modern cousin: same shape, but with an automatic column-wheel chronograph, the Co-Axial 3330, that Omega introduced in 2012 to bring its own escapement into the Speedmaster. The chequered minute track is the Racing signature, borrowed from a 1968 dial, and the small seconds sub-dial at six carries the date.

At 40mm it is smaller than the 42mm Moonwatch and thinner-looking on the wrist despite the 15mm height, because the case is more rounded. The tachymeter is on a black bezel rather than printed on the dial, and the bracelet is the flat-link Speedmaster bracelet in brushed steel.

Reading the listing

Rebag gives the case at 40mm and 15mm thick, the band at 19mm, a wrist size of about seven inches, steel case and bracelet, a black dial, an automatic movement with chronograph, date and tachymeter, the condition as Very Good with minor scratches and light wear on the case and band, and a dated warranty card. It does not give the reference. The 40mm steel Racing Co-Axial with a black dial on a bracelet is the 326.30.40.50.01.001, and the photograph matches it; the calibre and reserve here are Omega’s published figures for that reference. Ask Rebag to confirm from the card.

Nothing here was measured on this unit. The warranty card date will tell you the watch’s age; ask for it, and ask when it was last serviced.

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 Speedmaster Racings.

Speedmasters 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.

FAQ

No. The Racing is the automatic Speedmaster with the Co-Axial calibre 3330 and a chequered minute track; the Moonwatch is hand-wound. Same family, different movement and dial.
