What I'm asked about the Sinn Ladies Watches 434.020
What strap size does the Sinn Ladies Watches 434.020 take?
The Sinn Ladies Watches 434.020 needs 18 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Sinn Ladies Watches 434.020 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 Sinn Ladies Watches 434.020?
Yes, in 18 mm leather. On a 34 mm case a calf strap works every day; if you want something more, alligator.

A 18 mm calf strap, for every day. You'll find it ready in the 18 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
