Audemars Piguet 4158 Rectangular 1970s

Golden Geometry — A refined rectangular profile in pure 18k yellow gold.

This Audemars Piguet Ref. 4158 is the essence of understated 1970s elegance. Housed in a beautifully slim rectangular case, the watch features a minimalist golden dial with matching stick hands and indices — a timeless dress piece crafted to perfection.

The real standout, however, is the integrated 18k yellow gold bracelet, gently tapered and subtly patinated — a sign of age and authenticity that adds warm character. The case remains remarkably clean, likely protected in storage, with patina developing naturally on the bracelet.

Inside, the ultra-thin Caliber 2003, a legendary manual movement known for its precision and elegance, ticks away effortlessly. Recently serviced and keeping near-perfect time.

To top it all off, this piece comes with the original Audemars Piguet certificate booklet from its first sale in Osaka, Japan in the 1970s — a beautiful historic detail for any discerning collector.

A rare, warm, and refined slice of AP history.
