I am so glad I found your website, I have a Citizen eco-drive chronograph watch, not on par with a Rolex obviously. It looks fantastic with the rotaing bezel, but I didn't have a clue how to use it. It has markings from 10 to 90 minutes, (I think) then inside on the watch face are markings 10 to 90, but each marker has the minutes marked, it starts of like 1, 2, 3,4 etc upto 25 then the markings change to 30, 35, 40 etc upto 70. I read your Instructions, but to be honest I am still none the wiser, I shall print them out if that's okay. I can go through them carefully. Oh I forgot, you don't turn the bezel by hand, you have to use the crown on the lower left hand side. Thanks again, Happy New Year. Roger.
