Ware was the next day because, as usual, so quickly and easily. At first I was skeptical because it is an expensive clock. If it did not work and I had somewhat damaged by the polishing I would have for the new glass and expect the overhaul about 500.-. So starting with a slightly queasy feeling, but that soon disappeared. Since this was a deep scratch, I had the procedure repeated several times, but after the second passage of the scratches was visibly smaller. Overall, it took me about 15 minutes to the scratch to be completely disappear. Strong buy recommendation!
