Vintage Schatz Royal Mariner Ships Wheel Clock measures 13\" across whole piece, clock is about 6\" in diameter and 3.75\" deep. This item is estate fresh and came with no key. I do hear something that sounds like a screw rolling around inside. I have not taken this apart for lack of knowledge. You are buying as found for parts or repair. Wood finish show wear, face has a couple scuffs on it as well. See photos for details. A little TLC would make this a very special clock!
