Originally introduced in 1971, the ETA/PESEUX Cal 7001 (PESEUX merged with ETA in 1985) is a thin watch movement that is simple yet a class apart. This movement is often paired with either Swiss or German high-end wristwatch brands.

This is the JUNGHANS MEISTER calibre J815.1 hand wind movement, based on ETA/PESEUX 7001, containing 17 Jewels, 21600 vph, and has a power reserve of approximately 42 hours.

The movement was also used by Blancpain, Nomos, Stowa, Junghans, etc.
