The Girard Perregaux wristwatch showcased in today's offering is one of the company's sought after vintage models. This officially certified chronometer employed a long list of advanced technical features. It was so accurate, in fact, that 70% of the chronometer certificates issued in 1967 by the Neuchâtel Observatory were for these special high-frequency chronometers. Here are some of the watch's features:

* "High Frequency" 36,000 beats per hour balance system, twice the speed of many traditional wristwatches (most vintage watches beat 18,000 times per hour) and made to accommodate changes in temperature. For decades 36,000 beats per hour was as fast as any production watch ticked.

* Officially certified as a chronometer by the C.O.S.C

* Very effective Gyromatic system requires smaller wrist movement to keep the watch fully powered. This also helps the watch spend more time running at its peak power level which can give more accurate timekeeping

* Cool two-tone dial emblazoned with the observatory logo

* Rugged Super Compressor style case and crown

* Employ three different special patented technologies

In certain respects, these watches and Longines high beat chronometer were the best of the best when it came to accuracy in a widely-produced watch at the time.

The watch is fully original down to the dial, hands, bracelet, and signed winding crown, and the movement is clean.
