What I'm asked about the Hamilton Jazzmaster H89905330

What strap size does the Hamilton Jazzmaster H89905330 take?

The Hamilton Jazzmaster H89905330 needs 20 mm between the lugs. It's the size I've been fitting on it for years.

Can the strap on the Hamilton Jazzmaster H89905330 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 Hamilton Jazzmaster H89905330?

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 Hamilton Jazzmaster H89905330?

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.
