What I'm asked about the Longines Flagship L4.774.3.22.7
What strap size does the Longines Flagship L4.774.3.22.7 take?
The Longines Flagship L4.774.3.22.7 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 Flagship L4.774.3.22.7 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 Flagship L4.774.3.22.7?
Yes, in 18 mm leather. On a 36 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Longines Flagship L4.774.3.22.7?
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.
