Golf rounds often take a long time, especially in tournaments. Therefore the Royal Open Course Timer & GMT has a timer which tracks how long a round of golf takes for you and your course companions. It works using a rotating crown with which the outer hour ring can be turned and set to the starting time. The same mechanism can also be used to display a second time zone, so you won't miss the tee time at Pebble Beach.
