Unlike most ETA chronographs, the 2094 is not based on the Valjoux 7750. Rather, it is derived from the 2004-1 "ladies movement", itself based on the popular ETA 2892-A2. The 2094 is very compact for an automatic chronograph, measuring just 10½ lignes (23.30 mm) in diameter and 5.50 mm high. ETA claims that this calibre is intended for ladies watches and thin square or rectangular watches.
The 2094 is modular, with the 2004-1 top plate complemented by a complete chronograph plate. These can be manufactured and tested independently.
Mechanical chronograph movement with automatic winding, ball-bearing rotor, small seconds at the "9" with hacking seconds, date window at "4:30" with quickset feature. Calibre in ladies' size, used for instance in the Sinn 6030 Financial District Watch IV.
