My Omega Speedmaster Pro 3570.50 Moon Watch with the Hesalite crystal needed some TLC after three years of everyday wear. After choking on Omega's $500 watch cleaning price, I decided that I would settle for getting a new Hesalite crystal installed. When I went to my Omega dealer he said he could replace it for $80 or I could buy some Polywatch on the web for $10 and spend 10 minutes to make my existing crystal look like new.

He was right. Polywatch works. Really, really well.
