Wonderful all original condition on this Omega Seamaster Calendar in 14k gold fill. This is an early calendar watch for Omega and this one features an original finish dial with gold Arrow Head markers. Truly outstanding! Everything including the hands are genuine and original to the watch.

The movement is the Omega in-house caliber 502 with 17 jewels and adjusted to two positions. The signed Omega case is 14k gold filled and its reference number is KX-6725. The case measures 35mm across without the crown, and 42.25mm lug to lug. It is in great condition and far better than just about any other 58-year-old watch you are likely to see. The watch also features a signed Omega crown.

It has just received a full and complete service. Included in the service was a new mainspring and crystal. The watch is running great and keeping very good time. We lightly refinished the case before putting it through an ultrasonic cleaning.

Please take a look at the movement picture. You can certainly tell this watch has been well cared for. Better yet, look at of all the pictures and see its overall condition. One of the nicer examples of an early Omega Calendar with a 500-Series movement you are likely to find.

Comes complete with a new matte brown leather strap.
