Clock Depthing Tool

The clock gears are mounted on adjacent spindles and then meshed using an adjustment knob provided on the tool so that the two wheels are the correct depth and run smoothly. Having achieved a satisfactory result the tool is turned vertically and the clock plates are marked using sharp points which are located on the end of the spindles, normally protruding from the front of the tool. This ensures that when the pivot holes are drilled they are at the correct position for the clock arbors. Special thanks Steen Winther for gears from the ETA-6497 complete watch movement post.
