What I'm asked about the Hamilton Timeless Classic H38435721
What strap size does the Hamilton Timeless Classic H38435721 take?
The Hamilton Timeless Classic H38435721 needs 20 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Hamilton Timeless Classic H38435721 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 H38435721?
Yes, in 20 mm leather. On a 38 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.

A thin 20 mm alligator. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
