I recently overhauled this Ansonia walnut cased kitchen clock. The strong time mainspring of 0.018 inch thick, was causing wear to the mainwheel teeth, so I replaced the mainspring with a new one that is only 0.0155 inch thick (Merritt’s P-1496 in the orange and red box).
The first video below shows how good the escapement motion is with the thin time mainspring. It is run down 9 days in the video. The second video shows the entire movement in the case and then a closer view of the clock striking the hour and half-hour.
Repair job 4899.
