What I'm asked about the Patek Philippe Grand Complications 3448J

What strap size does the Patek Philippe Grand Complications 3448J take?

The Patek Philippe Grand Complications 3448J 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 Grand Complications 3448J 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 3448J?

Yes, in 18 mm leather. On a 37 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Patek Philippe Grand Complications 3448J?

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.
