Patek Philippe Square Case
Presenting a sophisticated 18k solid gold square case with a luxurious feel.
The Cal. 23-300 movement housed in this watch
is a versatile movement created to be slightly smaller to fit various case shapes, both square and round.
It boasts excellent accuracy and durability, and has a proven track record as a long-seller from the 1950s to the 1970s.
Not only that, but all parts have a perfectly formed and beautiful chamfered finish that will make you fall in love with them.
As an aside, chamfering on mid-range movements is flat because it is done with a diamond cutter,
whereas chamfering on high-end movements like Patek's is characteristically rounded.
The elaborate and luxurious construction, with attention to detail, exudes the dignity characteristic of a high-end product.
The crown features the brand logo.
This is a truly luxurious and special Patek square case that will keep your wrist looking stylish for years to come.
Don't miss this opportunity to own it.
