Description

De standard 22mm polyurethaan (PU) Strap that Seiko used for the SKX171 is identical to the strap of the SKX007, except the buckle is different. This buckle is even more classic, and is polished, Seiko used this buckle with the models with a all-steel bezel, like SKX171, SKX169, 7002-7020).
Polyurethane 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.
