The ready-to-wear strap is 115 × 75 mm. For a smaller or larger wrist I make it in the right length: order your length.

What I'm asked about the Hamilton Intra-Matic H38716731

What strap size does the Hamilton Intra-Matic H38716731 take?

The Hamilton Intra-Matic H38716731 needs 22 mm between the lugs. It's the size I've been fitting on it for years.

Can the strap on the Hamilton Intra-Matic H38716731 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 Intra-Matic H38716731?

Yes, in 22 mm leather. On a 42 mm chronograph I like box calf: it holds its shape and carries a substantial case.

Which strap do you recommend for the Hamilton Intra-Matic H38716731?

A 22 mm box calf. You'll find it ready in the 22 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
