We didn't research pictures or reviews of the museum, and didn't know what to expect. We just wanted to go there and knew we would not be disappointed.
We took a 2 hour guided tour visit, which is available in English and in French. A lovely and elegant lady welcomed us and guided us through 3 different floors on the museum. the 4th floor has
2500 time pieces, and some beautiful artifacts. All are in working condition. You will find an Antique collection (16th-19th century), and a Patek Philippe collection (1839 - present).
Surprisingly enough, the collection doesn't include only Patek Philippe watches. It include many watch brands including Breguet, and Sarton (article about Sarton here).
A visit worth much more the 10 CHF (swiss francs)
