I have had this item from new for the last 35 years and it is in good working condition, albeit that it has not been in use for the last twenty or so years. It does not have an original Omega band/strap. Any ideas of a value range for this item would be appreciated. At the moment I cannot seem to get some nice clear images to post and will continue trying. Thank you. Mark.
When you can post pics we can help you more. There were a few different versions of the Cosmic. Does yours have a strap or a bracelet? Is it date only or day & date?
I'll take a stab, but by no means am an expert on them, probably 300-500 USD depending on condition, here's a close-ish match that sold on ebay http://www.ebay.com/itm/c1972-OMEGA...sWatches_GL&hash=item35b8b1ea03#ht_500wt_1156Purchases made through these links may earn this site a commission from the eBay Partner Network
Looks like a 166.0130 with a caliber 1012. The earlier Cosmics with the 56x and 75x go for more money. Still, $200 to $350 is the ballpark for that one, maybe a smidge more if it's in better shape than can be discerned by that picture. The photo is too washed out so try taking one without the flash using indirect natural light, like near a window without too much glare.
