This is an incredible and attractive vintage Omega Seamaster Chronograph watch. Watch is working excellent (just serviced), and all chronograph features are working correctly. The manual wind chronograph movement is an Omega calibre 861 with 17 jewels. The movement serial number dates this watch to 1975—unpolished solid stainless steel case in excellent condition. The case measures 39mm across, excluding the crown by 42mm from lug tip to lug tip. The case model is 145.029. The original and signed acrylic crystal is in great shape, covering a clean stunning factory original blue finish dial. The dial does some dark aging coming out from the center. It will come with its original 22mm metal bracelet that will fit up to a wrist size of 7.5 inches. The wrist size in the photo is 6 inches. This watch will come with its original red box with outer cover box protection, and its original purchased Italian guarantee card from April 13, 1975. Card indicates the watch's case material and that it comes with a metal bracelet.
