Hello, I have a question, but some background first. My father, P.A.D.I. Master Instructor #007, owned a Sub 300t Sharkhunter which he wore everyday as I was growing up. Shortly before he retired he bought a Rolex Seadweller which became his daily watch. I had never worn a watch until the day after he died. I started wearing his Rolex. I beat the daylights out of it every 3rd day at work and after about a year I bought my own Doxa. I chose the Military Sub 1000t Professional. I chose the Military version so as dirt would not show up on it as much. My question, The black coating around the bezel and on the bracelet is scratched off. Is there a way to have the scuffs touched up? Another question off this topic. My Sub 1000t loses about 6-7 minutes a day. I realize this is not normal for a Swiss timepiece but, has anyone else experienced such bad timekeeping with their Subs?
