1985 Omega Vintage Seamaster Mens Watch, Ultra Thin Automatic, Date - 18K Gold Plated & Stainless Steel


Item No. 5639

Today's offering showcases this beautifully restored classic midsize Omega Seamaster from c. 1985. It is a very uncommon model with a fluted bezel on a rectangular case that has a great 80's look to it.

Built at a time when the quartz revolution was taking hold and Omega was cutting costs, this later vintage Seamaster with automatic Cal. 1110 movement with quick-setting date carried on the distinguished tradition of the mechanical Seamaster. It has a fine ETA based Omega ultra thin automatic movement with 21 jewels.

It presents in true expertly restored condition. It is 100% Omega down to the original hands, signed winding crown and crystal! The original dial has been beautifully refinished. The printing is perfect - it could pass as Omega factory done to the naked eye.

The movement is running true.

Included with the purchase is a one-year C.O.T. warranty on the movement and its function, a custom printed Connoisseur of Time Certificate of Authenticity, and a new timing certificate.

A very uncommon three decade old Omega that presents almost like new!
