Wow, after reading the reviews on this I thought there was about a 50/50 chance this would work on a Hesalit (brand name Acrylic crystal) on My Momentum LUGANO Automatic
watch. Its has alot of fine scratches in the center, and three deeper ones. In less than 40 second with light rubbing in a Horizontal motion -- the scratches were gone. I cant even see but the lightest trace of them with a loop. - It took very little of the product to achieve perfect results. HIGHLY RECOMMEND IT
