History and Significance
During the 1960s and 1970s, Audemars Piguet produced a wide range of extremely thin dress watches that reflected the brand’s long history of refined watchmaking in the Vallée de Joux. These “Extra Plat” pieces focused on elegant proportions and mechanical restraint, often housing very slim hand-wound movements inside minimal precious metal cases.
This example reflects that philosophy well. The rectangular case is executed in yellow gold with a clean brushed finish and sharp edges that give the watch a distinctly architectural presence. The dial is simple and classical with Roman numerals, slender hands, and the traditional “Audemars Piguet Genève” signature. Pieces like this were designed for formal wear at a time when ultra-thin dress watches represented the pinnacle of understated luxury.
Rectangular Audemars Piguet watches from this era remain appealing to collectors because they capture a different side of the brand. Long before the Royal Oak defined the modern identity of AP, watches like this represented the quiet sophistication that the manufacture had been known for since the 19th century.
Writer’s Thoughts
This is one of those watches that works because of its proportions. The rectangular case has presence but still feels very elegant on the wrist. The Roman numeral dial and the blued cabochon crown give it a very classic look that pairs well with a leather strap.
Pieces like this are easy to overlook next to the more famous sports models from Audemars Piguet, but that is part of their charm. It is a simple, refined dress watch from one of the most respected manufacturers.
