Editor's Notes

Bremont's 'ALT1-Z' series has long been a favourite of explorers, squadrons and those in aviation. Limited to just 15 pieces, this reference in blue for the first and only time features a durable stainless steel case and sleek bracelet strap, making it appropriate for daily wear and smarter events alike. It's engineered with modified Swiss mechanics, fine-tuned to chronometer precision, powering not on a stopwatch chronograph function but - crucially to a pilot - a second time-zone ‘GMT’ hand, showing the time in 24 hours anywhere else in the world.

We offer a two-year warranty for all working parts and manufacturing faults for luxury watches. Call our Customer Care team for more information.
