Collection: Rolex Datejust 31mm Watches (Midsize & Ladies)

The 31mm Datejust, often called the midsize, sits between the classic 26mm ladies' size and the 36mm, for anyone who wants a little more presence on the wrist. This collection gathers our pre-owned Datejust 31 watches, from vintage references such as the 6824, 68273, 68274 and 68278 to the 78240, 78274, 178240, 178271 and 178273.
