3 year warranty
Bremont focuses purely on beautifully made mechanical movements and every watch in our core collection has passed each of the rigorous precision tests necessary for the ISO 3159 chronometer designation. Every movement is finished to the highest levels of craftsmanship and all are guaranteed to within -4 and +6 seconds per day. For this reason Bremont is one of the few watch makers to offer at least a 3-year warranty on every timepiece.

Proudly made in the UK
Great Britain has a wonderful history when it comes to watch making and has probably been the home to more advances in horology than any other nation. Bremont is determined to play a pivotal role in the reinvigoration of this industry on British shores and as a result, Bremont manufactures parts at its Parts Manufacturing Facility and every Bremont is hand-build and tested before leaving the Henley-on-Thames workshop.
Description
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.
Brown vintage leather strap with solid deployment buckle and engraved security clasp.

REINVIGORATING THE BRITISH WATCH INDUSTRY
It is not completely unexpected to find that the world sets its time by Greenwich and not by Geneva. Whilst Geneva and Switzerland may be producing the vast majority of luxury wristwatches today, this certainly wasn’t always the case. In 1800 half of the world's watches, around 200,000 pieces a year, were produced on British shores by British watchmakers, which is an incredible statistic. Another wonderful statistic is that probably over 60-70% of the innovation in a modern day mechanical watch has come from Britain, including every major escapement design. Bremont's mission has always been to play a part in bringing back watchmaking to British shores.
