This fantastic 1970 Omega Seamaster Cosmic 166.036 is a excellent watch choice for any occasion. With its beautiful case lines first designed for Omega by Gerald Genta and its perfectly integrated steel bracelet, this Seamaster is larger in size and wears well on any wrist. The watch features an absolutely stunning textured silver dial that is possibly one of the nicest Omega has ever produced (check out the macro shots!). The watch also features beautiful hands, a day date display in English with cyclops magnification, a radially brushed case, and a brushed bracelet. The watch features sharp lines and OEM finishing. The watch has a new Omega OEM acrylic crystal, freshly cleaned hands and dial, a new bracelet with integrated end-links, and a beautiful Omega 752 automatic movement that has been overhauled and restored to OEM specs. This Omega Seamaster Cosmic is in beautiful restored condition as per our extensive restoration and authentication process.

This Seamaster features the beautiful Omega 752 automatic movement with day date and a push-pull quickset date. The beat rate for this watch is 19,800 vph. The 752 Omega movement was one of the last movements based on Omega’s 550 series which are arguably some of the most resilient vintage movements in existence. The watch is 36.5mm in diameter, but wears larger due to the case design and the bracelet. The new adjustable bracelet will fit wrists up to 8″ in diameter making it suitable for any wrist size. The dial, movement, crystal, crown, and case are all signed Omega. This watch is a 1-piece case design with a new crystal and features mid-range water resistance.

Note: The small indent marking on the crown side of the case is not a flaw or dent, it indicates that the watch was originally intended for the European market. This was a common practice at the time.

As with all our restored pieces we sell, this 1970 Omega Seamaster Cosmic comes with our zero-headache warranty.
