Fixing a crystal in 15 min

I bought this Skyliner in a sad condition, The bracelet was aftermarket and a mess the case was very dirty and I thought scratched en the crystal looked like it needed to be replaced..... But as you can see if you look at the hands, it took not long to make it look like a real watch. I never use watch products to polish a crystal or a case so maybe that is why it looks so good (I do use "meguiars" that is a car product) On the last picture the Skyliner sits on an Horween strap looking like a million bucks.

Please link what products you're using. I am building a small Seiko collection and learning the ropes.

Great restoration!
