Wonderful 24 hour maritime radio room clock that keeps great time. Face is marked "Geo E Butler Co., San Francisco. The case is in great shape other than someone ground the numbers off the back of the case (see photo 8). I don't think the key is original, but it works with it.

The clock measures 7.5 inches diameter mtg. flange, glass is 5.5 inches in diameter.

Really a nice one and hard to find.
