Here is a scarce and highly collectible vintage Omega timepiece. It's collectible for its rare jumbo size, measuring a large 39mm diameter, excluding the crown by 45mm lug tip to lug tip. The diameter of this size makes this watch appear like a pocket watch on a smaller wrist. The professionally serviced manual wind movement is an Omega calibre 283 and runs strong and accurately. The movement serial number is 11817256, dating this watch to 1949. The case is rose gold plated and in excellent unpolished condition. The rare case model is CK 2545-1. The factory original dial is perfectly aged and patina. Original set of leaf hands in very good aged condition—brand new crystal. Crown is original and signed. It will come with a 20mm new old stock vintage-style, high-quality genuine leather strap. The wrist size in the photo is 6 inches.
