These are the top of the line! The Chelsea Ship's Bell clock and barometer are hand-crafted with painstaking attention to detail. They are the Rolls Royce of marine instruments, famous around the world for their quality and integrity. Etched and silvered dials. Solid brass casing, made to last forever. Gold plated Eleven-jeweled mechanical movements. Each individual piece is uniquely numbered and registered, chiming every half hour up to 8 bells. The dog watch never looked, or sounded, so good.
