Hamilton H77615333 hands on GMT function
The Hamilton Khaki Aviation GMT Series is a reliable and affordable timepiece for anyone that wants to see the current local time as well as the GMT time. Ideally you set the main time (hands) to GMT / UTC (pull out the crown all the way to set this) and set the current crown by pulling out the crown half way and turning it clockwise, turning it counterclockwise will make it change the date. The crown on the left can be set to the current city the second time zone was set to or also to indicate the city of the main time zone. Last but not least the third crown can be used as a timer: align the minute hand and triangle on the bezel and the minute hand will indicate how many minutes have passed.
