The Hamilton Khaki Navy GMT is by no means restricted to underwater timekeeping. In addition to being water resistant to a depth of 200 meters (660 feet), the Khaki Navy GMT is capable of measuring time in two different time zones on dry land. A total of 24 cities on or near to the ocean are available for selection for a second time zone. The new Hamilton timepiece is the latest expression of an action-oriented and pioneering tradition dating back almost 100 years.
