Description

The standard 22mm PU (PolyUrethane) strap that Seiko used on the SKX007, SKX009 and SKX011. It is hard material and not flexible, the waves in it are there so it can be stretched a bit. It will get the round shape for your wrist in time, but you can speed up this process by putting it (made round as much as you want it with a piece of string or so) in really hot water
It is 22 mm wide between the lugs, the “shoulders” are 26,8 mm, and it tapers down to 20mm at the buckle.
