Description

The ETA 2671 was launched in 1971 and is still put into nearly every "swiss made" selfwinding ladies' watch. It bases on the selfwindig technology, which was developed in the 1950ies, but represents otherwise the technical status quo of the 1970ies with 28800 beats per second and the date indication with instant change and quickset in the second of the three crown positions.

The movement displayed here only used an axle beared rotor and 21 jewels, more expensive versions, which are sold today, all use a ball-beared rotor and 25 jewels. The most simple versions instead only contained 17 jewels and a rather rare Ruby-Neutro-Shock protection system.
