Bremont Altitude Skeletonised Perpetual Clendar GMT Limited Edition Stem Winding – ALT42-PER-TI-BLSKL-B

The BREMONT Altitude Skeletonised Perpetual Calendar GMT represents the pinnacle of the Altitude Collection—an extraordinary fusion of haute horology and aviation-inspired design, limited to just 50 pieces worldwide. Crafted in a lightweight 42mm Grade 2 titanium Trip-Tick® case, this rare timepiece features a brushed Air Force Blue skeleton dial that showcases the full architecture of its Agenhor-developed perpetual calendar and GMT mechanisms. The open-worked design reveals bridges, finishing, and intricate mechanical interplay, reinforced by structural blue arms that maintain rigidity while enhancing clarity across its beautifully arranged subdials.

A rotating globe at 12 o’clock provides intuitive 24-hour GMT functionality, while the radial date at 6, month and leap-year display at 3, and propeller-style running seconds at 9 offer a harmonious blend of complexity and legibility. Despite its impressive complications, all adjustments are made effortlessly through the integrated mono-pusher crown and discreet correctors.

Finished with a glassbox sapphire crystal and offered with both a titanium bracelet and a blue patina leather strap, this timepiece balances refined craftsmanship with everyday durability. Powered by BREMONT’s hand-wound BHC9192-MH movement with a 50-hour power reserve and chronometer-level accuracy, it stands as a testament to British design and Swiss watchmaking mastery. The Altitude Skeletonised Perpetual Calendar GMT is a sophisticated choice for collectors who seek the exceptional—mechanically, aesthetically, and in sheer rarity.
