Antique Seth Thomas U. NAVY BOAT CLOCK great for restoration needs. The case has its original unpolished patina. There Is an old bump on the ring. The glass has multiple cracks. The clock dial is loose and missing the key and clock hands. Sounds like there is something loose inside that slides around when you tilt it. This will make a worthy restoration project. Check out the photo’s for condition.

Deck clock in good condition. My dad believed this was off the USS Flasher. Upon removing the movement, the serial number is off by 1 digit from the one written on the tag. The number could have been misread, and this is the clock from the crew’s quarters but there is no way to be sure. My Dad passed last year and no doubt new of the discrepancy on the inventory tag and believed this to be off that sub. Either way it’s a beautiful piece of history.

Despite not having a key and being untested, this clock would make a unique and historically significant addition to any collection of maritime antiques. Small hand tip is broken off. Hands do move freely but untested other than that.
