The ALT1-Z Range

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 replaced GMT in 1972 as the international reference standard for communications, military, aviation, maritime and other activities that span multiple time zones.
