Bremont drops the NEW Altitude Perpetual Calendar GMT

Redefining Its Future

Bremont takes a bold leap forward in 2025, releasing a Perpetual Calendar GMT that signals a new brand direction. Long known for rugged, military-inspired tools, the British brand now targets the realm of high complications and refined mechanics. This isn’t just any Perpetual Calendar watch, according to their website it’s “Hand Built to order” and will take 10-12 weeks to dispatch.

A Higher Course for Bremont

Under CEO Davide Cerrato, Bremont is taking it up a notch. He isn’t playing it safe—he’s challenging expectations. Bremont no longer sticks solely to just utility made watches. Instead, it follows in the path of brands that play in the same space that have paved the way like IWC & Zenith, blending heritage aviation style with complicated Swiss movement work.

A Movement Built to Impress

Bremont built this watch around the AMT6900 base caliber from Sellita’s custom manufacturing division. Agenhor—a Geneva-based specialist—developed the perpetual calendar module. Together, they crafted a movement that blends performance and aesthetics. It features curved sunray finishing, Geneva stripes, polished bridges, and snailing. The open caseback reveals it all.

Aviation-Inspired Details Ground the Complication

Despite its complexity, this watch doesn’t abandon its roots. Bremont used RAF blue for the dial and the Trip-Tick center barrel. At 3 o’clock, a propeller-style month display spins with each passing month. A single red blade marks leap years. Another propeller tracks running seconds at 9 o’clock, while the date window sits at 6 o’clock.

Globe-Driven GMT Function with Purpose

At the top of the dial, a domed globe delivers the GMT functionality. A button inside the crown sets the display—cleverly making this a monopusher. The system isn’t typical for a GMT, but it feels smart and intuitive.

Titanium Case and Limited Numbers Add Exclusivity

So, how big is it? The case measures 42mm, built from lightweight Grade 2 titanium, just like the bracelet. It’s also available in a blue patina quick release strap. This material keeps the piece wearable despite the added mechanics. And how much does it cost? Bremont prices this release at £33,500 GBP, or around $42,000 USD. They’re only making 50 pieces, placing this firmly in collector territory.

Bremont Moves Beyond Tool Watch Territory

Bremont didn’t build this for the average enthusiast. It designed this watch to challenge its own past—and its competition. By delivering a perpetual calendar, GMT, and refined Swiss finishing, Bremont now competes with luxury names offering true haute horlogerie. This watch doesn’t just mark time—it marks a turning point.
