Here is a very attractive Omega Constellation Calendar watch.   Rare and clean factory original dial.  It is seldom to come across a dial this clean on this particular case model.  The crystal and case back gasket are brand new.  The case is made of solid gold bezel and case back medallion with gold capped lugs over solid stainless steel.  Pop open the case back and you'll have a very clean recently serviced automatic movement.  The tarnish on the movement is discoloration and not rust.  The 24 jewels automatic movement is an Omega caliber 504 with serial number 16725053 dating this piece to 1958.  Omega only made 25,000 pieces of caliber 504 which compared to most other calibers is consider a small production amount.  The case model is 2943 - 3 SC and measures 35mm across excluding the crown by 44mm lug tip to lug tip.  Case back has a few tool scratch marks.  Will come with a new 18mm croco grain genuine leather strap.  Wrist size in photo is 6 inches.
