What I'm asked about the Eterna Heritage 1938.41.45.1250
What strap size does the Eterna Heritage 1938.41.45.1250 take?
The Eterna Heritage 1938.41.45.1250 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 Eterna Heritage 1938.41.45.1250 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 Eterna Heritage 1938.41.45.1250?
Yes, in 20 mm leather. On a 36 mm chronograph I like box calf: it holds its shape and carries a substantial case.
Which strap do you recommend for the Eterna Heritage 1938.41.45.1250?
A 20 mm box calf. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
