Audemars Piguet Perpetual Calendar For Unique Timepieces

Audemars Piguet's Royal Oak Perpetual Calendar For Unique Timepieces, reference 26606ST.OO.1220ST.01, has a steel case measuring 41 mm across and 9.5 mm thick. The green dial carries the "Grande Tapisserie" pattern typical of the Royal Oak line and sits under a sapphire crystal. Inside is calibre 5134, a self-contained movement that drives the perpetual calendar complication, accounting for varying month lengths and leap years without manual correction. This is a limited edition of only 50 pieces, made specifically for the retailer Unique Timepieces, which makes it a scarce variant within the Royal Oak family. The steel bracelet closes with an AP folding clasp, and a green alligator strap is supplied as an alternative option. Water resistance stands at 50 metres.
