18ct Omega Grand Luxe Constellation Calendar watch dating from 1966 reference 14398
Here is a brief edited article taken in part from the Omega Museumâ€™s website about the Omega Constellation:
The progenitor of the Constellation line is without doubt the appropriately named â€śCenturyâ€ť. A limited edition self-winding chronometer wristwatch launched in 1948 to celebrate the firmâ€™s 100th anniversary. This watch, not intended for series production, was greeted with such enthusiasm that the decision was taken to create a watch with all the same qualities on an industrial scale. It started with the movements, which were all self-winding chronometers that had received the mention of â€śEspecially good resultsâ€ť during testing.
The line would soon develop into a series of watches which were finished to different degrees. The Constellation Deluxe was available in gold with applied gold indexes on the dial. And finally the Constellation Grand Luxe, which was available in gold and platinum with corresponding dial and the so-called â€śBrick linkâ€ť bracelet.
The form of the Constellation remained little changed until 1964 when the so-called â€śC-caseâ€ť watches were introduced. The name was a reference to the form of the case, which resembled two interlocked Cs. The change would also be incorporated in the first ladiesâ€™ Constellation, launched in 1967.
The 1970s saw the introduction of quartz technology to the wristwatch and this also applied to the Constellation line. Some of the most accurate watches ever produced in series were developed for the Constellation line, including the famous Marine Chronometer which is, to this day, the most accurate autonomous wristwatch and the only watch to be certified as a marine chronometer. However it wasnâ€™t a Constellation Marine chronometer that stunned the watchmaking world with a 0 error rating. It was a calibre 1021 self-winding movement destined for a Constellation that held the distinction of achieving absolute perfection when it received its certificate marked â€śEspecially good resultsâ€ť, showing a variation of 0.00 after 15 days of testing in five positions and at varying temperatures.
