The ETA 2675 watch movement, introduced in 1965, features a micro rotor and utilizes double jewel bearings if equipped with 30 jewels. It incorporates a double excenter regulator for curb pins and stud carrier. The self-winding gear includes a pinion floating between two substantial jewels, allowing for direction switching. The indirectly driven minute mechanism enables a low profile for the watch. Minor modifications to the base plate and simplified date driver were made subsequently around 1966/67. The movement of the ETA 2675 is automatic and includes a date function, set by changing the 23-24-hour range, which was changed to the 22-24-hour range around 1966/67. This movement has been used since 1965.
