The Valjoux 23 is a mechanical watch movement characterized by a Lubrifix-66 combined setting for the escape wheel. It shares a similar bridge layout and special balance with equivalent movements such as the Cyma 701, Doxa 87, Girard-Perregaux 26, and Zodiac 52. The Valjoux 23 movement features manual winding, a sub-second hand, and was primarily used around 1965.
