The Datejust 41 in blue, with a dated card.

The Datejust 36 is the watch Rolex built its reputation on: the first self-winding wristwatch with a date that changed at midnight, launched in 1945, and made ever since in a 36mm Oyster case with a screw-down crown, an automatic chronometer movement, the date under its Cyclops lens at three, a fluted, smooth or engine-turned bezel, and a Jubilee or Oyster bracelet. Because Rolex made it for eight decades in every dial and metal, the pre-owned market is deep and this is where the money goes when people search for a Rolex that is not a Submariner.

Rolex moved the men’s Datejust to 41mm in 2016 and gave it the calibre 3235, the movement with the Chronergy escapement and about 70 hours of reserve that now runs most of the Oyster line. The 126334 is the steel version with the fluted white gold bezel, and blue on the Oyster bracelet is the combination that sells fastest at retail. Rebag’s listing does not give the reference but the dated card does; the grade is Very Good, and the note about scratches on the crystal is one to ask about, since a sapphire crystal marks only from something harder than steel.

Rebag gives the case at 41mm and 12mm high, the band at 21mm, a wrist size of about 7.5 inches, the band and case as stainless steel, the dial colour as blue, an automatic movement with date and a screw-down crown, a dated warranty card as included, and the condition as Very Good with minor scratches on the crystal, minor tarnish on the case and wear on case and band. It gives no reference. The white gold fluted bezel and the Oyster bracelet are in the title and the photograph; the calibre 3235, its certification, the reserve and 100 metres are Rolex’s published figures for the 126334.

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 date on the card, whether the box is included, and when it was last serviced. Nothing here was measured on the watch. Ask for a close-up of the crystal scratches the listing mentions.

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 41mm Datejusts.

Steel and two-tone Datejusts 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.
