During the 1960s Omega made significant changes to the outward appearance of the Constellation. The slimmer bezel and slender lugs together with a more angular appearance brought it back into fashion. As a result, it wears larger on the wrist than its predecessor. This 1966 version has all these attributes and, for a watch that is some 60 years it, is in exceptional condition.
 
The Constellation range was exclusively chronometers. Every watch had to be tested in an independent laboratory and had to run at a high level of accuracy at different temperatures and in different positions. So high was the quality of Omega microengineering that few ever failed. Only watches that had passed this test could be signed chronometer on the dial - as in this example.
 
One of the more rare dials where all the hours are represented by numbers (Arabic). Each gold-coloured number has a chamfered finish and is individually applied. Gold hands with black inserts. Sweep seconds hand. Applied Omega and logo in gold. The finish on the dial is all original and is excellent for a 60-year-old watch. Quick-set date at 3. Unmarked acrylic. Semi-concealed crown. This is an automatic watch that harnesses the energy of the moving wrist to wind it up.
 
The case is gold capped with a solid gold bezel. The condition is very good. The case-back is a screw fit. In the centre of the back is an 18k gold medallion featuring an observatory and 8 stars. The definition of this medallion is sharp meaning the watch has had relatively little wrist time over the years.
 
Inside is the in-house manufactured Omega 562 calibre. Runs as it should!
 
The watch is fitted with a new, non-Omega, brown leather strap.
