An ultra-capable adventure tool for pilots and explorers alike

The 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).

This watch maintains the clean legible dial with the 24hr function having been moved to the bezel for improved clarity. Greater detailing around the stepped sub dials with micro lines on the ZT models has been made to give the dial more depth. This reference is fitted on a brown vintage leather strap with solid deployment buckle and engraved security clasp.
