## Description

Bremont Alt42-Per-Ti-Blskl-B Altitude Perpetual Calendar Gmt SKELETONISED ALTITUDE PERPETUAL CALENDAR GMT MONOPUSHER EXCLUSIVELY UNVEILED AT DUBAI WATCH WEEK Bremont is proud to unveil a skeletonised edition of the Altitude Perpetual Calendar GMT Mono-pusher celebrating the beauty and ingenuity of the exclusively designed Agenhor movement within. First introduced at Watches & Wonders 2025, the model unites two legendary complications in one supremely robust, perfectly engineered timepiece. Crafted from lightweight grade 2 titanium and featuring the Altitude collection’s signature three-piece Trip-Tick case construction, the model is built for those who demand refinement, resilience and practicality. PERPETUAL PERFORMANCE The Altitude Perpetual Calendar seamlessly integrates a GMT function without compromising the Altitude Collection’s aviation-inspired sportiness, everyday usability, and visual clarity. The openworked dial displays complex information with exceptional legibility, while decorative arms in Air Force Blue lend structural support to the subdials — preserving both the durability and distinctive design language of the Altitude range. At 12 o’clock, a domed globe disc – echoing that previously seen in 2024’s Terra Nova Dual-Time Tourbillon – provides the second time-zone indication: as the globe turns, an arrow indicates the home time against a 24-hour index that’s divided into day and night sections. Adjusting this is straightforward: a mono-pusher integrated into the crown allows the wearer to advance the arrow in one-hour increments. A corrector at 2 o’clock allows you to set the date, whilst a corrector positioned at 4 o’clock allows you to set the leap year and month. At 9 o’clock, running seconds is displayed with a lume-tipped two-blade ‘propeller’ hand, on a sector-style subdial. The perpetual calendar’s indications – date, month and position in the leap year cycle – are presented on the other two subdials, at 3 o’clock and 6 o’clock respectively. At 6 o’clock, a pointer indicates the date on a radial index. At the 3 o’clock position, a beautifully intuitive month/year indication uses a four-blade propeller-style hand, with three white-tipped blades and one red-tipped blade. The subdial is divided into four sectors, each representing a year in the leap cycle, while the first sector also includes markings for the 12 months. The red-tipped blade denotes the current position in the four-year cycle, while the month is shown by whichever of the four blades is passing through the first sector at any given time. The propeller’s movement is imperceptible, advancing in 172 micro-jumps across the four-year cycle – a shift of just under 2.1 degrees every eight day. SKELETONISED ELEGANCE Bremont’s first Perpetual Calendar GMT Mono-pusher demanded the best in Swiss engineering and British craft. The complication module was created exclusively for Bremont by Agenhor in Geneva, masters of ingenious mechanics. Founded in 1996 by horological visionary Jean-Marc Wiederrecht, Agenhor has earned numerous accolades for its groundbreaking innovations, featured in timepieces from esteemed brands including MB&F, H. Moser & Cie, and Hermès. The Perpetual Calendar GMT monopusher complication truly showcases Agenhor’s mastery and through stripping back the solid dial of the original Perpetual model, the skeletonised edition showcases the original architecture and elegant simplicity of the module. The exquisite ‘Côtes de Genève’ finish is visible across the module’s bridges and a beautifully engraved Wayfinder logo features on the lever of the mono-pusher. The base calibre is a manually wound movement - the AMT6900, produced within Sellita’s top-tier, custom-build AMT (Atelier Manufacture Technique) programme. The combined movement measures just 6.8mm — keeping the case a lean 12.65mm. Davide Cerrato, Bremont CEO, comments: “The skeletonised Altitude Perpetual Calendar GMT takes the complexity of this watch and makes it tangible, visible, and captivating. It allows collectors to see the interplay between the GMT and perpetual calendar complications, while retaining all the robustness, usability, and distinctive character of the Altitude Collection.” With its open-worked architecture, highly engineered complications, and aviation-inspired design codes, the Skeletonised Altitude Perpetual Calendar GMT Mono-pusher stands as a pinnacle of Bremont’s watchmaking, appealing to enthusiasts who value both mechanical mastery and contemporary visual impact.
