Here's a very special solid 18k gold rectangular Omega Constellation automatic. The original signed crystal is in very good condition. The unpolished case on this watch is made of solid 18k gold and has personal engraving on the back. The case model is 151.024/153.029 and measures 24.5mm across, excluding the crown by 38.8mm lug tip to lug tip. This is a dress watch and would look perfect on a smaller wrist size—original signed crown. The factory original is in very good condition and is made of solid 18k gold. Inside the case, there is a movement holder, which is made of metal and not gold. The automatic movement is an Omega calibre 672 and has been recently serviced. The movement serial number is 27454279, dating this watch to 1968. The watch will come with a new 16mm croco grain genuine leather strap. The wrist size in the photo is 6 inches.
