The Bremont ALT1-Z was designed with aviators and world travellers in mind. Z stands for ‘Zulu Time’ and allows the wearer to display local time together with the official world time standard – Universal Time Coordinated (UTC), Greenwich Mean Time (GMT), or even Zulu time (Z).

UTC (replacing GMT in 1972) is therefore used as the standard clock of choice for international reference time in communications, military, aviation, maritime and other activities that cross time zones. This is one of the primary reasons why the Bremont ALT1-Z has become the watch of choice for the professionals involved in these activities, including many Military Squadrons.
