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 just under 35mm in diameter without the crown, about one millimeter smaller than a Rolex Datejust.

Its dial has been previously refinished to look like a military style Seamaster wiht a Railmaster/Ranchero style. The watch presents in gorgeous condition. It is fully Omega down to the hands and winding crown.

Its movement, originally adjusted to two positions at the factory, has just been serviced by our watchmaker including installed a new genuine Omega pallet fork, and it is running extremely true. Photos of the inside available upon request.

For the finishing touch we have equipped it with a brand new crocodile strap making it ready for immediate enjoyment.

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.

The Seamaster:
Omega is perhaps best known by watch connoisseurs for its Seamaster line of dive watches. Introduced in 1948, they have been were embraced by water sports enthusiasts and often marry a striking look with a high performance movement.
