Bremont ALT1-Z

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 incorporating a modified Valjoux 7754 undertaken with peerless execution, has become the watch of choice for the professionals involved in these activities. The watch case integrates an internally rotating bezel operated by a crown on the left-hand side of the watch.
