Omega Constellation Jumbo COSC Chronometer Cal.564 Ref.168.018 35.0mm 1968

Up for sale here is a stunning vintage Omega Constellation in stainless steel freshly serviced and in near perfect condition.

Starting with the dial. The dial comes flawless with a beautiful sunburst effect playing brilliantly in the light. This comes paired with the stunning applied black coloured steel indices and iconic constellation star, creating a beautiful sparkle in the light. Not to mention the sharp and sleek dauphine hands that play brilliantly in the light. On top of that stunning dial would be a rare Original Omega cyclops eye crystal with a miniature Omega logo in the middle, difficult to see without a keen eye.

Moving on to the case starting with the bezel. The bezel comes in a stunning radial brush with a professionally polished faceted mirror finish. Creating a stunning crisp shine at various angles. This faceting is also reflected on the lugs, with a stunning mirror finish paired with the brushed edges. Coming together in a mesmerising light show. In addition, at the 3 o’clock position sits its original signed crown with the Omega logo.

Turning the case over one would reveal Omega’s iconic Observatory icon on the case-back, representing the constellation line which is still in use till today. It comes with a crystal clear mirror polish so good one could use it as a pocket mirror.

Inside the case is Omega’s well regarded Cal.564 automatic movement that has been certified to run at chronometer standards under the revered COSC association. The watch has just been serviced in March 2025 by a professional watchmaker and runs at an excellent ~0s/day, fitting within even the modern COSC chronometer standard of between -4.0s/day to +6.0s/day. All of this is no mean feat for a watch of this age, showcasing its excellent condition. 

Additionally, the 564 movement comes with a quickset date function. Where when you shift the crown from the second to third position the date moves forward once, and the process can be repeated till the correct date is shown. Do make sure not to use the quickset date feature when the time is between 9pm to 3am.

As an added bonus the watch comes with a sleek black aftermarket crocodile leather strap with an aftermarket stainless steel Omega buckle. Included together would be a 1-month warranty card and a PolyWatch crystal polishing kit as part of our complimentary watch care package.
