What I'm asked about the Longines Conquest Heritage L1.650.4.52.2
What strap size does the Longines Conquest Heritage L1.650.4.52.2 take?
The Longines Conquest Heritage L1.650.4.52.2 needs 20 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Longines Conquest Heritage L1.650.4.52.2 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 Conquest Heritage L1.650.4.52.2?
Yes, in 20 mm leather. On a 40 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.
Which strap do you recommend for the Longines Conquest Heritage L1.650.4.52.2?
A thin 20 mm alligator. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
