A nice early 60's classic Omega Constellation Chronometer with white crosshair dial with onyx set hour batons, quite striking.
 
This watch has beautiful symmetry, with the crosshair balancing the non date dial. 
 
The watch has light wear, some small marks to the case and dial but overall it is very good.
 
The watch comes paired with its original red leather box, and strap and buckle. 
 
A classic!
