Here we have a Dynamic 166.039 that is in great shape considering it was manufactured from the late 1960's through the 1970's. Given it's vintage nature, there are signs of ordinary wear as well as patina (natural aging) on the hands and dial. Pictures are part of the description so please refer to the pictures in determining the condition, pictures are of the exact watch being offered. There are not many of these automatic 18k Dynamics around, especially with the blue bullseye dial. The case is made of 18k yellow gold, mostly displaying a satin finish with the exception of the sides which have a mirror finish. It is currently mounted on an Omega Corfam blue leather strap that is paired with an Omega 18k yellow gold tang buckle. Time and date are displayed on a blue dial that is accompanied by an off-white ring giving it the nickname bullseye. This watch has passed through our service center where it was first checked inside and out to certify its authenticity. After that, it passed a functionality test to confirm it is running up to manufacturer's standards. The watch is NOT water resistant. Lastly, the serial number was run through a database to verify its legitimacy. We will issue receipts and a certificate of authenticity and test it once again prior to delivery. This watch will be backed by our in-house warranty.
