What I'm asked about the Seiko Prospex SSC957

What strap size does the Seiko Prospex SSC957 take?

The Seiko Prospex SSC957 needs 21 mm between the lugs, usually 18 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the Seiko Prospex SSC957 be changed?

Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.

Can I put a leather strap on the Seiko Prospex SSC957?

Yes, in 21 mm leather. On a 41.4 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Seiko Prospex SSC957?

A 21 mm calf strap, for every day. You'll find it ready in the 21 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
