The Westclox 2 watch movement, manufactured in Germany, was considered to be the sole German movement with chronometer capability during the period of 1952 to the present. These movements underwent testing at the Deutsche Hydrographische Institut Hamburg, which likely contributed to its reputation. Early samples of the movement featured two recesses on the base plate for different shock devices. The Westclox 2 movement is a manual wind movement that includes a sweep second hand.
