Watches and Wonders 2025: Bremont elevates its Altitude collection with the Perpetual Calendar GMT Mono-pusher

Building on its legacy of aviation-inspired timepieces, Bremont unveils four new models in its Altitude collection with a combination of unusual complications in the Altitude Perpetual Calendar GMT Mono-pusher.
Continuing the legacy of creating capable tool watches, Bremont has launched 4 new models in its Altitude Collection. From the Altitude Perpetual Calendar GMT Mono-pusher, featuring dual complications to the Altitude MB Meteor, inspired by Britain’s first jet fighter with ergonomic design improvements, each timepiece reflects meticulous engineering. 

Altitude Perpetual Calendar GMT Mono-pusher

Elevating the brand’s aviation inspired lineage, the Altitude Perpetual Calendar GMT Mono-pusher features, as the name suggests, a perpetual calendar and a GMT. The timepieces come in a 42mm lightweight grade 2 titanium featuring the collection’s signature three-piece Trip-Tick case construction. Inside, the ‘Air Force Blue’ dial are four sub-dials. Housing GMT, a sub-dial at 12 o’clock indicates the second time zone. Reminiscent of 2024’s Terra Nova Dual-Time Tourbillon, the sub-dial features a domed disc with a globe’s image on it and a white arrow-shaped pointer. 

As the globe turns, the arrow indicates the home time against a 24-hour index that’s divided into day and night sections. Adjusting this is simple: A mono-pusher integrated into the crown allows the wearer to advance the arrow in one-hour increments. A recessed corrector at 2 o’clock allows you to set the date, indicated in a sub-dial at 3 o’clock;  whilst a recessed corrector positioned at 4 o’clock allows you to set the leap year and month, indicated in a sub-dial at 6 o’clock. In a sector style sub-dial at 9 o’clock, a two-blade propeller hand displays running seconds. 


A manually wound base Calibre AMT6900 powers the watch and offers 50 hours of power reserve and water resistance up to 100 meters. 

Designed for everyday wear, the watch is 12.65mm thick, including the base movement and complication module. A limited collection of 50 pieces, the timepieces come in two options for straps: A titanium bracelet and a blue patina leather. 

Altitude MB Meteor

Taking inspiration from Britain’s very first jet fighter – Gloster Meteor – Altitude MB Meteor integrates frontline materials, improved ergonomics, and significant technical advancements. 

Like the Perpetual Calendar GMT Mono-pusher, this model also comes in a 42mm Grade 2 titanium in a three-part trip-tick design but with a slimmer profile and reduced lug-to-lug distance, making it wearable everyday. The watch comes with dual crowns, one at 2 o’clock for winding and setting, and one at 4 o’clock for operating the bi-directional inner bezel. There is a date window at 3 clock. A new concave, angled bezel is paired with a ‘glassbox’ sapphire crystal. The dial is available in two colour options – black and brushed silver – with numerals and indexes coated high-grade Super-LumiNova offering optimal visibility and clarity.

The watch features a ‘lollipop’ seconds hand counterbalanced by a looped ‘ejection’ pull handle in white and black stripes, inspired by a military aircraft cockpit: a stencilled motif for the numerals, and a dashed line around the date window.


The timepiece is powered by the robust BB14 movement, derived from La Joux-Perret’s G100 automatic calibre, offering 68-hour power reserve visible through its open case-back. 

Bremont debuts a refined brushed titanium bracelet with quick-release functionality, designed for flexibility and comfort with curved bars. For a more personalized look, the MB Meteor is also available with a textured leather strap or a handcrafted Bremont NATO strap.

Designed as an ultra-durable tool watch for everyday wear, the 39mm Trip-Tick case, featuring a single crown, is crafted from high-grade 904L stainless steel. Powered by BB14 calibre, this model also offers 68-hour power reserve visible through its open case-back. The watches are available in black or brushed steel dial variants, with a choice of 904L steel bracelet or nubuck leather box-stitch strap. 

Altitude Chronograph GMT

Combining chronograph and GMT functionality have long been a staple of Bremont’s lineup, Altitude Chronograph GMT is another addition to this lineage. The 42mm Trip-Tick case is made from ultra-rugged 904L stainless steel. Inside, the watch is powered by the chronometer- rated BC781 automatic movement, with a 62 -hour power reserve, quick-set date and GMT, and hacking seconds. 


There is a small seconds counter at 9 o’clock, a 30 minutes chronograph small counter at 12 o’clock, a 12 hour counter at 6 o’clock. There is also a date window at 6 o’clock. For the first time, the Bremont’s Wayfinder logo appeared at 3 o’clock on a dial.

Finished in black or brushed silver dial variants, the watches come with a choice of a bracelet, leather, or NATO strap.
