Made in the mid 1970s — the heyday of the Golden Ellipse, this ref. 3545 was made from 1967 and remained in the line for a decade. The two-piece cases were made by Baumgartner (Geneva key mark 2). The bracelet is sized for a 6 3/4 inch diameter wrist.
Collectability says
“At Collectability, we see the ref. 3545 as an under-appreciated gem in Patek Philippe’s catalog. For those who admire the daring designs of the 1970s, it offers both rarity and huge value. Take a close look at the coral pattern on the mesh bracelet – now that is true 70s beauty.”
