The Omega Constellation Watches line dates back to 1952,
when Omega created this line that housed the highest-grade chronometer movements they produced.
This is still the case today for the Omega Watch Constellation line.
The following watches are the highlight of this line.
The 38mm Chronometer line now carries the 8500 co-axial movement.
This line has a case diameter of 38mm and an integrated bracelet.
The 188.8.131.52.01.001 shown on the right has a transparent case back providing a view of the beautiful mechanism.
The 35mm Chronometer line is very similar in looks to the 38mm line, only that it houses the 2500 co-axial movement.
The 35mm line also exists with a quartz movement.
This line houses the 1532 movement and officially cannot be called a chronometer watch, since a chronometer cannot have a quartz movement.
It also does not have a display back.
Last, but not least, is the double eagle chronograph.
While the other watches in the Constellation line have an integrated metal bracelet, the Double Eagle has a rubber strap.
It houses the 3313 co-axial chronometer movement that has chronograph and date functions.
My favorite dial layout is the 1819.51.91 shown below.
