Sorna Automatic German slide rule watch 3 rotating bezels GMT Diver Tachymeter. Has 2 inner rotating bezels, one for GMT - world time with cities names, and the second for 60 min dive time. The outer rotating bezel is slide rule for km/h to knots (for aviation I believe), and has tachymeter scale as well.The two inner bezels are rotated by thr two crowns on the left side of the watch. In addition to the seconds hand (red longhand on pic), has date number, day name of week and month name on the dial. These are adjusting by the crown on right side (time and date), and pushers on the side (day of week and month name). I bought this during a vacation trip in Germany but nevet put it on, the plastic wrap is still around the bracelet. Have tens of watches in my collection and know how to take care of them.
