SIGNED AUDEMARS PIGUET, QUANTIEME PERPETUEL MODEL, REF. 5551BA, MOVEMENT NO. 225'472, CASE NO. B 56116, NO. 350, SOLD IN 1981

Extremely rare and seldom produced, the present Audemars Piguet Quantième Perpétuel reference 5551BA is a highly unusual and relatively unknown watch to even the most astute collectors. Confirming the present watch as reference 5551BA and dating it to the early 1980s, the brand stated that these special timepieces were often made on special order and in extremely small numbers.

The present watch features an onyx and diamond-set octagonal bezel, an incredible and impossibly rare combination which resemble the shape of Maison's legendary Royal Oak model. Furthermore, the glossy white dial have blue sapphire indexes which complement the blued calendar hands and moon phase. Another star of the show, the robust, yet supple woven gold bracelet is made by Jean-Pierre Ecoffey (JPE case stamp), one of the greatest and most celebrated bracelet masters. With the combination of the gold construction, stone-settings, and 38 mm. size with a thinness of only 7.5 mm, this superb timepiece is well-suited for a broad array of wrists, making the present 5551BA a deluxe wristwatch to enjoy for the ages to come.
