This listing is for a vintage 8 day Nautical clock marked Chelsea Clock Co. Boston, U.S. Maritime Administration. 

It is in very good condition and keeps good time.

The key that is included is not an original but it works.

It’s made in solid brass with a 6” silvered clock face and it weighs 7 pounds.

This clock measures overall, 7-1/4" in diameter and 3-1/4" tall. 

This model has a second hand and a speed regulator.

The glazed window unscrews to gain access to the winding mechanism.

This clock could use some polishing and removal of some paper label residue on the back.

Please read my description and look at the pictures carefully to make sure what you are bidding on, is what you expect to get.
