For sale, I have an Omega Constellation C-Case reference 168.017. It has the Caliber 564 and based on the serial number it should be from 1968. The case has some dings and scratches but still retains all its lines and doesn't appear to be polished. Watch is working fine but not sure how well it is keeping time since I never wore it long enough to find out. I don't have any service history but looking at the movement I would say it needs one. The dial looks a little dirty not sure what it is or if it would come off after service. The watch will come with your choice of either a new Brown or Black leather strap. You can also have a bracelet for an additional fee if you like. If you need more pictures let me know. I’m asking $450 USD for this watch which does not include shipping. I will ship insured. Accepted payment methods are wire transfer or cash. Watch is located in Toronto. F2F deals in the Toronto Area are welcome at a police station. I will offer a return if I have made any major mistakes in my description of the watch. Below some references from the forum. Thank you OF for the space https://omegaforums.net/threads/toishome-is-a-great-seller.98344/ https://omegaforums.net/threads/toishome-good-transaction.99341/ https://omegaforums.net/threads/toishome-is-a-great-seller.100159/ https://omegaforums.net/threads/toishome-is-a-great-seller.90737/ https://omegaforums.net/threads/good-business-with-toishome.88150/ https://omegaforums.net/threads/toishome-smooth-transaction.62422/
