1960s Audemars Piguet 18K White Gold Rare Ribbed Design Square Case with Ribbed Dial
This is a distinctive timepiece featuring a ribbed dial and case—a design rarely seen even among Audemars Piguet watches. The bezel and mid-case, though appearing as an integrated unit, are actually part of a three-piece construction. A unique serial number is engraved on the bezel, mid-case, and case back, indicating their matching origin.
Although compact at 25mm, the square case gives it a strong wrist presence. Combined with the solid gold construction and bold, original design, the watch offers a substantial and commanding feel far beyond its dimensions. It is equipped with the beautifully decorated Caliber K2001, featuring Geneva stripes, beveled edges, and regulation in four positions—a precious and rare piece that blends craftsmanship with unique aesthetics.
