Jaquet Droz 69

Caliber 69 is an automatic movement produced by Jaquet Droz and launched in 1960. It was manufactured under the Standard Coopérative arrangement, indicating it was sourced as a shared ebauche rather than developed in-house. The movement features a tonneau-shaped profile, reflecting design preferences common in 1960s watchmaking. It was discontinued at some point following the Quartz Crisis. This caliber represents Jaquet Droz's use of external movement suppliers during the pre-quartz era, a standard practice among Swiss brands that did not manufacture their own mechanical calibers.
