The 1970s were a time of artistic freedom and bold experimentation across music, film, and design—and watches were no exception. Audemars Piguet fully embraced the spirit of the decade, pushing boundaries with innovative shapes, sizes, and dial designs. While the Royal Oak often takes center stage, the brand’s creativity extended far beyond its iconic sports watch, as evidenced by this striking and unconventional timepiece.

Sold in 1973, according to Audemars Piguet archives, this watch features a sleek white gold case with a unique oval-cushion shape, measuring an impressive 41mm in length. The absence of lugs, with the strap integrated directly into the case, enhances its bold and modern aesthetic. The dial is equally captivating—appearing black at first glance, it shifts to dark grey or even blue depending on the angle of light, creating a dynamic and ever-changing visual effect.

Inside beats the ultra-thin Audemars Piguet caliber 2121, a technical marvel of its time. Measuring just 2.45mm thick, it was the world’s thinnest automatic movement when it debuted, showcasing the brand’s commitment to both innovation and precision.

Preserved in wonderful condition, this watch is a perfect blend of distinctive design and mechanical sophistication, making it a standout piece from one of horology’s most creative eras.
