What I'm asked about the Patek Philippe Golden Ellipse 3738/100J-012
What strap size does the Patek Philippe Golden Ellipse 3738/100J-012 take?
The Patek Philippe Golden Ellipse 3738/100J-012 needs 18 mm between the lugs. It's the size I've been fitting on it for years.
Can the strap on the Patek Philippe Golden Ellipse 3738/100J-012 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 Golden Ellipse 3738/100J-012?
Yes, in 18 mm leather. On a 31 mm case a calf strap works every day; if you want something more, alligator.
Which strap do you recommend for the Patek Philippe Golden Ellipse 3738/100J-012?
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.
