What I'm asked about the Hamilton American Classic H11421014
What strap size does the Hamilton American Classic H11421014 take?
The Hamilton American Classic H11421014 needs 18 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Hamilton American Classic H11421014 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 American Classic H11421014?
Yes, in 18 mm leather. On a 23 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.
Which strap do you recommend for the Hamilton American Classic H11421014?
A thin 18 mm alligator. You'll find it ready in the 18 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
