Today's offering showcases this very cool vintage Seamaster 600 mens watch. The 600 series was named because of the movement that powers the watch. Besides being hand-wound, a less common trait for a Seamaster, the Seamaster 600 also features a slightly thinner case than automatic Seamasters.

It measures 34.5mm in diameter without the crown, about the width of a Rolex Date watch (a millimeter and a half smaller than a Rolex Datejust).

It has been meticulously restored as part of a true expert restoration and presents as mint condition. It is fully Omega down to the hands and winding crown. The dial has been expertly refinished and the quality of the printing could pass as Omega factory done to the naked eye.

The caliber 613 handwound movement is adjusted to two positions. As part of the restoration it has been freshly fully serviced by a Master Watchmaker and is running very true.

(Note that the rose colored plating came out looking a different tone in the photos from how it appears in person).

For the finishing touch we have installed a new leather strap.

Included with the purchase is a one-year warranty on the movement and its function, a custom printed Connoisseur of Time Certificate of Authenticity, and a new timing certificate attesting to the watch's performance.

A four decade old Omega that presents like new!
