White Ceramic Royal Oak Perpetual Calendar, 26579CB.OO.1225CB.01
July 2019, Dubai, UAE: With summer in full swing, Swiss Haute Horlogerie manufacturer Audemars Piguet enriches its collection of Royal Oak Perpetual Calendars with a new hand-finished white ceramic model.
This new white ceramic Royal Oak Perpetual Calendar follows on from a previously introduced black version, highly praised for being durable yet light, sporty and elegant. Challenging to master but virtually unscratchable, white ceramic resists high temperatures, thermal shocks and ageing. Numerous operations demanding patience and skill are required to achieve a uniform, compact and ultra-hard material that can be machined and hand finished.
The watch’s white ceramic bracelet, like the case, has been beautifully finished with alternating satin-brushed and polished surfaces and is complemented by a titanium AP folding clasp.
The timepiece is endowed with a blue “Grande Tapisserie” dial, enriched with silver-toned day, date and month counters. The dial also features the astronomical moon indication at 6 o’clock, the week of the year transferred on the blue inner bezel and the leap year indication – pioneered by Audemars Piguet in 1955 – at 12 o’clock. White gold applied hour-markers and Royal Oak hands with luminescent coating complement the patterned dial.
Housed in a 41 mm case, the watch’s selfwinding calibre is fully visible through the glareproofed sapphire crystal caseback.
“To break the rules, you must first master them.”
