What I'm asked about the Sinn Ladies Watches 434.011

What strap size does the Sinn Ladies Watches 434.011 take?

The Sinn Ladies Watches 434.011 needs 18 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 Sinn Ladies Watches 434.011 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.

Yes, in 18 mm leather. On a 34 mm case a calf strap works every day; if you want something more, alligator.
