This is well featured and completely silent. It has 4 speeds or rotations per day settings, can be set with 3 directionals for a variety of watches but both bays will always be set the same. One quirk however is the bays don't move at the same speed. It's hardly different but after a few rotations the top and bottom won't be in the same position they were in relative to each other. Hasn't affected the winding so I'm not bothered
