What I'm asked about the Hamilton Timeless Classic H38715731

The Hamilton Timeless Classic H38715731 needs 16 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Hamilton Timeless Classic H38715731 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 Timeless Classic H38715731?
Yes, in 16 mm leather. On a 42 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.

A thin 16 mm alligator. You'll find it ready in the 16 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
