What I'm asked about the Patek Philippe Grand Complications 5004P-064

What strap size does the Patek Philippe Grand Complications 5004P-064 take?

The Patek Philippe Grand Complications 5004P-064 needs 21 mm between the lugs, usually 18 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 5004P-064 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 5004P-064?

Yes, in 21 mm leather. On a 37 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 5004P-064?

A 21 mm box calf. You'll find it ready in the 21 mm collection. If you'd rather have something built on your wrist, the Casati atelier.
