Among the wide range of watch complications available, the GMT is one of the most useful – particularly for frequent travelers. Modern GMT movements can keep track of two time zones simultaneously (and a third with just a few clicks of the bezel).

The Tudor Black Bay GMT<\/a> was well received by watch enthusiasts, admired for its handsome looks, topnotch quality, value for money, and real-life practicality.<\/p>\n\n\n\n

Reading the Tudor Black Bay GMT<\/h2>\n\n\n\n

One of the basics of knowing how to use a GMT watch is first understanding how to read it. On the dial of the Tudor Black Bay GMT, there are four hands: a red 24-hour hand, a white 12-hour hand, a white minute hand, and a white seconds hand. The white hour hand makes one complete rotation every 12 hours, while the red hour hand makes one complete rotation every 24 hours.<\/p>\n\n\n

The three white hands indicate local time while the red hand indicates reference time by pointing to the 24-hour marked bezel. The two colors of the bezel are intended to help users differentiate between night hours and day hours, where the numbers in the red section represent daylight while the numbers in the blue section represent darkness. There is also a date window at three o’clock, which indicates the local date.<\/p>\n\n\n\n

If you’ve set the Tudor Black Bay GMT accordingly while traveling, the red hand and the minute hand will tell you what time it is at home (reference time), while the white hour hand and minute hand will tell you the local time at your present location.<\/p>\n\n\n
