The usual references are the 36 mm 16013 and 16233 in two-tone and 16014 in steel, the 31 mm 68273 and the 26 mm Lady-Datejust 69173, mostly from the 1980s and 1990s and mostly on the five-link Jubilee bracelet. A steel 116234 can land here too, and so can vintage pieces such as an Oyster Speedking on a strap.
To buy one well, ask when the watch was last serviced, since these references run on earlier movements than today's. Read the card for custom dial, custom diamond set or aftermarket strap, the words that mark parts or stones not from Rolex, and ask to see it running on video. What a pre-owned Rolex costs and how to read the card are in our guide, and the real-Rolex checklist covers the rest.
Every Datejust from 36 mm up is on our Datejust page, the 26, 28 and 31 mm on women's Datejust, and everything else on the Rolex page. Final sale applies to every watch. Text 212-872-9692 for the desk; a person answers from 10 AM ET. TraxNYC, on 47th Street since 2004, is not a Rolex affiliate.
