XR7 Quartz Clock Conversion Guide

The pieces that come with the kit. You will want to replace the original red gear in the image above with the gear provided in the kit.


The video below goes over replacing the gears and washers onto the new Quartz movement

Place the movement aside. Back to the backing, you’ll want to remove the original brass cup washers and rubber grommets off the backing and replace them with the new ones in the kit. Wider diameter of the new grommet goes on the side of the backing with all the gears, narrower side goes toward the movement.

You can now attach the quartz movement to the backing. It really can only go one way, but in the video I point out the gears that need to line up.

Next up, push on the new lock washers over the rubber grommets to secure the movement in place. You have to make sure these are compressed tight. This was the most time consuming part of the restore/conversion.



I will continue the write-up in a follow-up post which will include reassembly, replacing the clock lens, and replacing the the light bulb diffusers.
