The  Universal Genève  from the early 1970s, as confirmed by the serial number 3512854. As a horology expert, I can tell you this watch is a triple-threat of collector appeal. First, it was designed by the legendary Gérald Genta (the same genius behind the Patek Philippe Nautilus and Audemars Piguet Royal Oak). Second, it houses the groundbreaking Caliber 2-66, which at its release was the thinnest automatic movement in the world at just 2.5mm thick.

The architecture is quintessentially elegant, utilizing an Ellipsa style stainless steel case and a signature Gay Frères integrated mesh bracelet that drapes like silk on the wrist. The magic lies in the Micro-rotor winding system a technical soul that allows for an ultra-slim profile while maintaining the convenience of an automatic movement. The sunburst silver dial, minimalist markers, and thin baton hands represent the absolute pinnacle of Swiss "Shadow" series aesthetics.
