Here is an uncommon vintage Omega Constellation watch dating to 1968 according to its movement serial number: 27269592. It's uncommon because this is the only Omega Constellation with the Pie Pan dial in a uni-shell case, meaning the movement can only come out from the front after removing the crystal. This watch has been professionally serviced, running strong and accurately. The automatic movement is an Omega calibre 564 with 24 jewels. The movement has a quick-set date feature. The factory's original finish dial is in well-aged condition. The case is in its original unpolished condition. Original signed crown. Original signed acrylic crystal in very good condition. The case model is 168.025 and measures 34mm across, excluding the crown by 38.7mm lug tip to lug tip. Watch will come with a matching high quality 18mm genuine leather strap. Wrist size in photo is 6 inches.
