This one should be easy. Unscrew the crown and pull to position 1 (sets date), position 2 sets time. When you pull the crown to position 2, it should hack the second hand (small subdial at 6:00). Rotate the crown to set the hour and minute hand.I have been given a Tag watch with number CA1211-Ro stamped to the rear, unfortunately it is running behind time. Could someone pass on the instructions on how to set the time correctly and operate the Chronograph:thanks.
