History

Georges Agassiz, son of Louis Agassiz, started the watchmaking business as Agassiz fils in 1876. He sold high-value, finished watches, often co-branded with Longines (where his father had worked) and Tiffany & Co. The company was later merged into Wittnauer, and Longines acquired the Agassiz trademarks in the 1980s. The most famous Agassiz movement is the Cal 9 ½ movement for the World Time. 

Technical details

Agassiz manual winding movement with 18 jewels and 6 position adjustments (Chronometer grade). The movement is numbered 209907. I believe this movement was also used for pocket watches.
