Patek Philippe x Tiffany & Co.

This is the Calatrava Ref. 3919, a representative model from the 1980s to 1990s.

This model features a Clous de Paris guilloché bezel composed of pyramid-shaped lattice patterns.

It is, in fact, a classic bezel design that has been in use since 1934.

This particular model was sold exclusively at Tiffany boutiques in the United States at the time, and its dial bears the "Tiffany&Co." inscription.

The mere presence of this inscription imbues it with an intense sense of distinction.

This is a complete set, including the original box, guarantee, and all other accompanying items from that era.

With a size of 33mm, it strikes a perfect balance, neither too large nor too small, wouldn't you agree?

A complete set of a co-signed timepiece truly is satisfying.
