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
- Jeweled with 39 rubies to reduce friction between the moving parts
- Elegant, waterproof style case
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 with a beat frequency much higher than that of Rolexes from the era.
It is fully original down to the dial, hands, winding crown, and case whose back is thicker than on most similar style watches. It untouched dial is just short of mint. And so is its case. It has one short remnant of a scratch to the back from previous opening. It presents beautifully on the wrist.
One of our watchmakers has disassembled it down to its last screw and cleaned and oiled it making it ready for immediate enjoyment.
For the finishing touch we have equipped it with a brand new crocodile strap making it ready for immediate enjoyment.
Included with the purchase is a one-year C.O.T. warranty on the movement and its function, a custom printed Connoisseur of Time Certificate of Authenticity, and a new timing certificate.
