These movements can be used with or without a sweep second hand. If you order a sweep hand we will send an open nut that will allow you to use all three hands..

The American "I" shaft hand configuration is fairly easy to identify without measuring the mounting holes. On all American "I" shaft movements, the mounting hole in the minute hand is "oblong with two flat sides", and the hour hand hole is round. The American "I" shaft configuration is used on most (but not all) battery and electric movements. It is not used on mechanical movements. The American "I" shaft configuration also requires a small round nut (included with movement purchase) to hold the minute hand in place.
