The Rolex Datejust 31 Stainless Steel/ Rose Gold / Domed - Diamond / Grey / Oyster takes a 16 mm strap: measure between the lugs and that is the only number you need. We list 29 straps in that width. A dress watch by proportion: a slim leather strap, plain or lightly stitched, keeps the line clean. With a 31 mm case and 100 m of water resistance, a strap of medium thickness keeps the balance. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
We do not sell watches. This page exists to find the straps that fit this one.
