What I'm asked about the Hamilton Khaki Navy H64512132

What strap size does the Hamilton Khaki Navy H64512132 take?

The Hamilton Khaki Navy H64512132 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 Hamilton Khaki Navy H64512132 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 Khaki Navy H64512132?

Yes, in 21 mm leather, as long as you don't wear it in the water: leather doesn't like the sea or the pool. For days in the water, rubber. On a 42 mm diver I go for a full-thickness strap, not a thin one. I don't keep rubber ready in 21 mm: write to me and I'll make it.

Which strap do you recommend for the Hamilton Khaki Navy H64512132?

Rubber if you wear it in the water; otherwise a 21 mm calf strap, full thickness. You'll find it ready in the 21 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
