Model History
The ALT1 designation — short for "Altitude" — is born in 2007 with the ALT1-Z, described by the brand itself as its first military GMT chronograph: a watch designed for the aviator who must simultaneously read elapsed time and a second time zone, the two most requested functions in the cockpit. It is with this reference that Bremont, still a young manufacture founded only five years earlier, begins to become known among a broader enthusiast audience beyond the military niche of the Martin-Baker project launched the same year.
The line's name, and its instrumental setup — a legible dial with Arabic numerals inspired by onboard instrumentation, a multi-counter chronograph, an internal Roto-Click® bezel for a second time zone — are also a direct tribute to the founders' father, Euan English, who had flown for the Royal Air Force at the controls of Spitfire PR Mk XIX reconnaissance aircraft: a biographical bond Bremont has always openly claimed for this collection, designed more than any other as a true "working tool" for those who fly.
In 2015, on the occasion of Baselworld, the line is rethought with the ALT1-ZT, a reinterpretation of the original project with an updated case and greater legibility; the following year brings the ALT1-ZT/51, which combines the ZT's setup with an aesthetic inspired by the vintage P-51 model. Over the years the ALT1 family has been enriched with variants dedicated to specific flight needs — from pure chronography to dual time zone, up to the world timer — remaining the most recognizable line in the Bremont catalogue for the broad audience of pilot's watch enthusiasts.

Main Executions
The designation "ALT1" recalls the English word "altitude": a direct reference to the world of flight that makes this line, born in 2007, the most explicitly dedicated to the memory of the founders' father among all Bremont collections, including those that later emerged from the collaboration with Martin-Baker.
