It was time to leave work, I visited the toilet and on my way out caught my Apple Watch stainless steel model on the door. One deep scratch with a pointy bit sticky up, and a deep scratch in the /bottom middle of the stainless steel and near the sapphire display. Annoying but I had nothing to lose. Sapphire hard as diamond! apparently! Well, here are the steps I used! 1. brillo pad scratches (which remove the sticky up metal) 2. nail file the remaining scratches (not a metal one but a sandpaper type material one) 3. autosol the area until shiny I wish I had taken photos because the scratches have virtually gone and they were quite deep. Also, i did brillo pad and nail file the screen (it was hard not to) and the sapphire has not one single mark on it! If I had the sport watch I would have to get a new one. I bet if I polished it more, I could remove the scratches completely. So, don't baby the watch, use it, if it's scratches, it's easy to fix! Stainless steel model anyway!
