What I'm asked about the Longines Master Collection L2.357.4.78.3
What strap size does the Longines Master Collection L2.357.4.78.3 take?
The Longines Master Collection L2.357.4.78.3 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 Longines Master Collection L2.357.4.78.3 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 Longines Master Collection L2.357.4.78.3?
Yes, in 18 mm leather. On a 34 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.

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.
