A Tribute to Legacy and Innovation

At the forefront of AP’s anniversary collection is the Royal Oak Perpetual Calendar Openworked “150th Anniversary.” Limited to just 150 pieces, this timepiece serves as a bridge between tradition and modernity.

Design and Materials

• Case and Bracelet: The watch features a 41mm titanium case, complemented by a bracelet that combines titanium with Bulk Metallic Glass (BMG) mid-links. BMG, an alloy containing over 50% palladium, offers a unique aesthetic and enhanced durability. This material choice not only provides a contemporary look but also ensures the watch’s resilience against daily wear.

• Dial: The sapphire dial offers a transparent view into the watch’s intricate mechanics. Blue sub-dials and an inner bezel, inspired by a historic AP pocket watch, add a touch of vintage elegance. The 18k white gold applied hour markers and hands, coated with luminescent material, ensure readability in various lighting conditions.

Movement

• Caliber 5135: Powering this masterpiece is the Caliber 5135, an openworked version of the renowned Caliber 5134. Operating at 19,800 vibrations per hour, it offers a 40-hour power reserve. Notably, this movement features a suspended barrel and an openworked oscillating weight that moves along a peripheral ring with ruby rollers, reducing friction and enhancing longevity.

Availability and Pricing

Given its limited production, the Royal Oak Perpetual Calendar Openworked “150th Anniversary” is a coveted piece among collectors. Priced at CHF 175,000, it stands as a testament to AP’s commitment to blending artistry with horological mastery.
