This big yellow gold-filled 18 size Elgin vintage pocket watch could not be any cleaner and has a stunning engine-turned back. The case is the higher quality J. Boss from Keystone, one of the finest case makers at the time. Made in the USA by Elgin in 1912. Winds, runs, sets and keeps time, but has not been serviced. Perfect double-sunk dial with large Arabic Numbers. No hairlines, chips or cracks. Hinged front and back. Covers all really snap shut sharply with a real snap like they've barely ever been opened and closed. All case serial numbers match. Old pendant-setting watch. There is just one very slight indentation on the back. 

Please review all of the pictures, they are a large part of the description. Big and masculine largest 18 size pocket watch that just screams elegance. Has a nice weight to it. Features a Grade 336 movement with 17 jewels with rubies and sapphires. Moseley regulator and Breguet hairspring.

We use a strong macro lens for our photos, which may make imperfections appear larger or worse than they actually are. Pictures are all magnified 2.5X to 5X.
