The ETA caliber 2094 is the perfect choice for smaller watches, or watches that want an automatic movement but have little case space to work with.
This ETA caliber 2094 was found in a Hamilton Jazzmaster Face2Face watch which has dual automatic movements. Because of the double movement design, small movements were necessary. The small size is a notable feature of the 2094.
The caliber 2094 is basically an ETA caliber 2004-1 base with a chronograph module added to it. The caliber 2004-1 is essentially a smaller 2824-A2.
