What I'm asked about the Patek Philippe Grand Complications 1518J

What strap size does the Patek Philippe Grand Complications 1518J take?

The Patek Philippe Grand Complications 1518J needs 19 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 Grand Complications 1518J 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 Grand Complications 1518J?

Yes, in 19 mm leather. On a 35 mm chronograph I like box calf: it holds its shape and carries a substantial case.

Which strap do you recommend for the Patek Philippe Grand Complications 1518J?

A 19 mm box calf. You'll find it ready in the 19 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
