Audemars Piguet is no stranger to pushing the boundaries of haute horology. The AP Royal Oak Perpetual Calendar Openworked in Titanium and BMG (Bulk Metallic Glass) is an extraordinary creation. This limited-edition masterpiece combines avant-garde materials. It features the brand’s legendary skeletonized perpetual calendar movement. This makes it one of the most striking Royal Oaks ever created.
A Fusion of Materials: Titanium Meets BMG
The first thing that sets this Royal Oak apart is its innovative combination of materials. The case and bracelet are crafted from lightweight titanium, known for its durability and resistance to corrosion. However, what truly makes this model special is the BMG bezel.
Bulk Metallic Glass (BMG) is an amorphous metal alloy that offers superior strength, scratch resistance, and a mirror-like finish. Unlike traditional metals, BMG’s non-crystalline structure enhances its resilience, making it an ideal material for a watch that’s meant to last generations. This is the first time Audemars Piguet has used BMG in a Royal Oak, marking a significant innovation in the collection’s history.
Skeletonized Perpetual Calendar: A Mechanical Marvel
Inside, the watch is powered by the Caliber 5135, an ultra-thin automatic movement that drives the perpetual calendar. The skeletonized execution showcases the movement’s intricate gears, levers, and finishing, making the timepiece as much an artistic statement as a technical one.
The perpetual calendar complication displays:
- Day, date, month, and leap year cycle
- Astronomical moon phase
- Week indication
Designed to account for leap years, this complication will accurately track the calendar without requiring manual correction until the year 2100.
Design and Aesthetic Appeal
True to the Royal Oak’s signature look, this special edition maintains the classic 41mm case size and the beloved integrated bracelet. However, the contrast between the satin-brushed titanium and the polished BMG bezel gives the watch a unique, futuristic appeal.
The openworked dial features a skeletonized slate-gray movement with black accents, creating a bold, technical aesthetic. The luminescent white gold hands and hour markers ensure legibility, while the moon phase display, featuring a hyper-detailed moon print, adds a poetic touch.
Limited Edition Rarity
To commemorate Audemars Piguet’s 150th anniversary, this Royal Oak Perpetual Calendar Openworked is produced in an extremely limited quantity—a move that guarantees its desirability among collectors. Given the brand’s history and the increasing demand for special editions, this watch is poised to become a future classic.
