The case appears here in a 41mm diameter and 12.4mm thickness made out of either yellow or white frosted gold. This frosted finish is also known as a “Florentine finish”, which consists of hammering gold repeatedly until it morphs into an evenly textured surface, with a sparkly appearance. It was introduced to AP by the Italian jewelry designer, Carolina Bucci, who utilizes a diamond-tipped tool to create a layer of tiny indentations that give the metal surface a frosted look, hence the names origin.On the flip-side is a sapphire exhibition case back, which allows a view into the inner workings of the mechanical movement. Unlike many of the other anniversary releases the gold oscillating weight has a carved out “AP” logo, instead of the “50” years emblem.Mounted to the case is the iconic octagonal bezel, held in place by 8 exposed screws. It comes equipped with two solid push-pieces that activate the chronograph functions, while between them lay protecting crown guards and the screw-in setting crown. All topped by a glare-proofed sapphire crystal that hangs over a peaceful clear sky-like hue. Water-resistance on this watch can reach up to 50 meters (164 feet).
Time is exhibited on a silver grey or yellow-toned dial (that matches each model's case material) with the “Grande Tapisserie” pattern and 18k gold applied hour index markers. While circling around the periphery is a ring of white or black printed second markings and longer minute markers.It features three snailed sub-dials: a 12-hour counter counter at 3 o’clock, a sub-seconds at 6 o’clock, and a 30-minute counter at the 9 o’clock position. Plus a date window has been placed between the 4 and 5 o’clock spots.
On the upper-half of the dial is the long-form "Audemars Piguet" logo in gold, matching each version's case alloy. The 18k white or yellow gold hands and hour index markers have all undergone a luminescent coating, for an enhanced legibility.
