This is an incredible and attractive vintage Omega Seamaster Chronograph watch. The watch works excellently (just serviced), and all chronograph features work correctly. The manual wind chronograph movement is an Omega calibre 321 with 17 jewels—the movement serial number dates this watch to 1966—unpolished solid stainless steel case in very good condition. The case measures 35.3mm across, excluding the crown by 41mm from lug tip to lug tip. The case model is 105.005. The original and signed acrylic crystal is in great shape, covering a stunning original factory finish dial. You can see minor marks on the dial, but the most distinct is next to the 2 o'clock marker. It will come with a new original 18mm genuine leather strap. The wrist size in the photo is 6 inches.
