What I'm asked about the Seiko Prospex SRQ045J1
What strap size does the Seiko Prospex SRQ045J1 take?
The Seiko Prospex SRQ045J1 needs 20 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.
Can the strap on the Seiko Prospex SRQ045J1 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 SRQ045J1?
Yes, in 20 mm leather. On a case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Seiko Prospex SRQ045J1?
A 20 mm calf strap, for every day. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
