Agassiz Watch Co. S.A. was founded in 1876 and specialized in high-quality watches. A new calibre was designed based on regular 19”’ watch movements, smaller in diameter and as slim as technically possible. The firm designed entirely new and even thinner movements: first 17”’- 24/12th, then 20/12th and 17/12th. Later, Agassiz merged with Touchon & Co., Geneva, which specialized in very thin movements.
