What I'm asked about the Hamilton Khaki Navy H74511133
What strap size does the Hamilton Khaki Navy H74511133 take?
The Hamilton Khaki Navy H74511133 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 Hamilton Khaki Navy H74511133 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 H74511133?
Yes, in 20 mm leather. On a 40 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Hamilton Khaki Navy H74511133?
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.
