Hey WatchFam, Up for sale is a fantastic piece of watchmaking history: a vintage Girard-Perregaux Gyromatic with the rare and specific reference number 4054RA. This is a true "high beat" watch from the late 1960s to early 1970s, a testament to Girard-Perregaux's innovative spirit during a pivotal time for mechanical watch movements. About the Watch: This vintage Girard-Perregaux stands out with its bold, angular stainless steel case, a hallmark of the era's design. The silver-white dial features applied stick hour markers and a date window at 3 o'clock. The "High Frequency" text on the dial isn't just a detail, it signifies the advanced 36,000 VPH (Vibrations Per Hour) automatic movement inside (not serviced). This incredibly fast beat rate was a major technical achievement at the time, designed to deliver superior timekeeping accuracy and a remarkably smooth sweep of the seconds hand. The watch is in genuine vintage condition, showing wear on the case and the acrylic crystal, aftermarket strap ,which gives it a characterful patina. It's currently running well for its age, but as with all vintage timepieces, a professional service is recommended for optimal performance and long-term reliability. It is presented on a complementary aftermarket black leather strap.
