It contains about 2,500 watchmaking items and related materials spanning 500 years of history. The Patek Philippe Museum houses not only Patek Philippe watches, it is probably the largest watch museum.

The initial exhibits for placement in the museum were specimens from the family collection, as well as from everything that Philip Sternberg collected. 

Today, the museum offers four floors of watchmaking, including a library with over 8,000 works.
