So trying out the polywatch glass polish on my grandfather's watch. 1st picture is the before 2nd picture is after step 1 (repair) 3rd picture is after step 2 (finish). Initial thought. I knew some of these scratches were never going to come out since they were too deep or wide. A lot of the minor scuffs did come out. The crystal used to be rough to the touch, now it is smooth again. I'm pretty impressed with the results. I'm not sure I'm brave enough to try it on my TAG Heuer Carerra that got a couple minor superficial scuffs on the crystal, especially since it has AR coating on the outside of the crystal. But for minor repairs on cheaper watches this will work just fine.
