Prepare to be captivated by the Bremont Altitude Perpetual Calendar GMT Mono-Pusher Skeleton, a timepiece that dares to expose its intricate soul while maintaining the rugged elegance Bremont is renowned for. But here's where it gets controversial: does revealing the movement's complexity enhance or detract from the watch's functionality as a tool? Let’s dive in and explore.
Bremont, a brand synonymous with aviation-inspired tool watches, has soared to new heights with its Altitude collection. After the experimental Terra Nova series, the British marque refocused on its core strengths, delivering a cleaner, more aviation-centric lineup that seamlessly integrates high-end complications. At the pinnacle of this collection sits the Altitude Perpetual Calendar GMT Mono-Pusher, a masterpiece powered by an Agenhor-developed module. For Dubai Watch Week 2025, Bremont takes a bold step by unveiling a skeletonised edition, stripping away the dial to showcase the movement’s artistry.
The watch retains Bremont’s iconic 42mm Trip-Tick case in grade 2 titanium, a design that blends brushed and polished surfaces with a PVD-coated middle barrel. Despite housing a high complication, it remains a true sports watch, with a manageable thickness of 12.65mm, a lug-to-lug measurement of 49.62mm, and 100m water resistance. A glassbox sapphire crystal protects the dial, while an open titanium caseback offers a glimpse into the mechanical heart. The mono-pusher is cleverly integrated into the fluted crown, with recessed correctors at 2 and 4 o’clock for calendar adjustments.
The most striking transformation occurs on the dial. The original solid RAF-blue face is replaced by an openworked blue structure, framing the Agenhor movement rather than concealing it. Applied numerals and indices, mounted on a skeletonised chapter ring and filled with white Super-LumiNova, ensure legibility against the intricate backdrop. And this is the part most people miss: the perpetual calendar’s month and leap year indication at 3 o’clock features a four-blade propeller hand that advances in 172 micro-steps over a four-year cycle—a testament to Agenhor’s ingenuity in disguising complexity.
Powering this marvel is the calibre BHC9192, a fusion of Sellita’s AMT6900 manual base and the exclusive Agenhor module. This slim 6.8mm movement operates at 28,800 vibrations per hour, boasts a 50-hour power reserve, and is regulated to -6/+6 seconds per day. The skeletonised design reveals Côtes de Genève finishing on the bridges and an engraved Wayfinder logo on the mono-pusher lever—subtle details that justify the open dial.
The Skeletonised Altitude Perpetual Calendar GMT Mono-Pusher comes with a quick-release titanium bracelet and a blue patina leather strap, both equipped with matching titanium hardware. Priced at GBP 37,000, it’s available through Bremont and authorized retailers. For more details, visit Bremont.com.
