Very attractive late 1950s Omega Seamaster Calendar watch.  Collectors would refer this model to as the Beefy Lugs Seamaster with a calendar feature.  It is also the first calendar Seamaster with the date feature at 3 o'clock.  The rare black gilt factory original dial is very well-aged.  Professionally serviced automatic wind movement working strong and accurate.  Omega calibre 503 with serial number 16526013, dating this watch to 1958.  The unpolished original gold capped over solid stainless steel case measures 34.3mm across, excluding the crown by 42mm lug tip to lug tip—original signed clover crown.  The case model is 2849 - 7 SC.  Brand new acrylic crystal.  All of its original luminous is still there on the dial and hands, but it no longer glows—brand new case back gasket.  The watch is ready for daily wear and will come with a high-quality new 18mm genuine leather strap. The wrist size in the photo is 6 inches.
