The Casio EFV-640DC-3AVUEF takes a 24 mm strap: measure between the lugs and that is the only number you need. We list 83 straps in that width. A dress watch by proportion: a slim leather strap, plain or lightly stitched, keeps the line clean. With a 44 mm case and 100 m of water resistance, a thicker strap balances the case. Quartz movement. 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.
