The Rolex Datejust reference 6636 is a 31mm timepiece in Yellow Gold presented in used condition, with a Custom White MOP Dia VI dial, Diamond bezel, Leather bracelet, dated circa 1959. This piece is customized — aftermarket-modified (setting or dial added outside the manufacturer); not original factory condition. Every watch is inspected and authenticated by our specialists before it is offered, so you can buy with confidence.
Choosing a Datejust means weighing size first: 26mm and 31mm for smaller wrists, the 36mm unisex benchmark, or the sportier 41mm. Material follows, from Oystersteel through two-tone Rolesor in yellow gold or Everose to solid gold. Each combination carries its own price logic. We handle authentication in-house and talk you through what to verify, so the reference you pick is the one you can trust. Read the full Datejust buying guide ›
Few names carry the recognition of Rolex, the benchmark by which most mechanical watches are measured. Established in 1905 by Hans Wilsdorf, the Geneva manufacture earned its standing through waterproofing, self-winding movements, and date displays. When a reference reaches us, we authenticate the Oyster case and Perpetual movement before it goes on sale. Demand outpaces supply here, and steel sports models routinely command premiums on the secondary market. Browse all Rolex ›
