Ich biete eine Omega Constellation Marine Chronometer f-2,4MHz in einem wirklich guten Zustand an
The most accurate wristwatch in the world. Still today, the Megaquartz 2400 is, indisputably, the most accurate, the most technologically advanced wristwatch in the world.
Developed by OMEGA in collaboration with the Battele Institute of Geneva, the first prototypes (cal. 1500) were presented at the Basel Fair in 1970.
It was first introduced on the market in 1974 (calibre 1510). Its unmatched precision of one second a month is around 10 times superior to that of an ordinary quartz watch.
This precision results from a specially designed tiny disc-shaped resonator, sealed in a capsule, which vibrates at the incredible rate of 2,359,296 times a second ! The high frequency earned one version, calibre 1511, the title of Marine Chronometer from the astronomic and chronometric observatory of Neuchatel - a unique award.
After 63 days of rigorous testing, the mean variation rate was no more than 2 thousandths of a second per day ! In addition, the Megaquartz 2400 was the first watch equipped with a time-zone-and-second-adjustment device for changing the hour without affecting the minutes or the seconds, for fine second adjustment and for synchronizing the seconds with an official time signal. Thus, for the first time in watchmaking history, the seconds were given their full importance.
Accurate enough... But what is not stated on the Omega web site is :
Only two 151x calibers were used in the Marine chronometer 2.4 MHz...
Caliber 1511 and 1516.... were the "Marine Chronometer" grade versions of the 1510 caliber Megaquartz 2.4 MHz.
Preis: 2350,-€ VB
