This watch is an amazing example of Constellation Electroquartz f8192Hz, in mint condition, presented with its original documents and box.
About the model
In the early 1970s, the watch world was about to be blown away by the cheap Japanese quartz watches. 20 Swiss watch companies collaborated together to create the Beta 21 movement. Swiss watch manufacturers were hoping their version of quartz technology would be their silver bullet against the imminent threat that was the Japanese quartz movements developed by Seiko. The Swiss conglomerate was composed of Bulova, IWC, JLC, Longines, Patek Philippe, Rolex and most famously Omega.
As mentioned in the Omega documentation from the early 1970s, this caliber is called “f8192Hz” because it is controlled by a tiny bar of quartz which, when stimulated by an electric current from its mercury power cell, vibrates precisely at 8,192 times per second. The significance of high speed vibration is simply this: the more finely it splits the second, the more accurate the watch becomes. A micro-miniaturised integrated circuit reduces the 8,192 vibrations to the slow pace of the hands of the watch and the practical result is a degree of accuracy unprecedented in modern timekeeping: within 5 seconds a month.
Note that the price of this watch was 1.920 CHF in 1972, 4 times more expensive than a Speedmaster Professional Moonwatch with a price of just 490 CHF…
