The Seiko Prospex Land SRPA77K1 Stainless Steel / Black / Strap takes a 21 mm strap: measure between the lugs and that is the only number you need. We list 216 straps in that width. Built for water, it wears naturally on rubber or a nylon NATO; a leather strap keeps it for dry days. With a 42 mm case and 100 m of water resistance, a thicker strap balances the case. 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.
