Omega Navigator 600 Medieval Seamaster Omega Seamaster 600 A beautiful sunrise dial, unpolished. Good and precise movement work operation. All accessories are original. Mechanical watches, despite the vicissitudes of history, still perfectly retain the smooth and gentle winding function of Omega. There is a small dent on the upper left lug and minor scratches on the dial. After asking a Swedish watch antique dealer, I learned that this watch is 60 years old, so it may have been opened and repaired along the way. But in the short three years I've had it, I can vouch that it has been fault-free and repair-free, and everything is working perfectly. Other than that, the watch is in good condition. All are original accessories. Cal 601 Ref 135.011 Serie. 2205***** 1965 Size 34-35mm (excluding crown) New leather strap (pictured) Can be sent with insured shipping if need.
