What I'm asked about the Patek Philippe Calatrava 5120/1J-001
What strap size does the Patek Philippe Calatrava 5120/1J-001 take?
The Patek Philippe Calatrava 5120/1J-001 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 Patek Philippe Calatrava 5120/1J-001 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 Patek Philippe Calatrava 5120/1J-001?
Yes, in 18 mm leather. On a 35 mm dress watch alligator is the natural choice: thin, elegant, what it was born for.
Which strap do you recommend for the Patek Philippe Calatrava 5120/1J-001?
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.
