Light strong and durable, this clock features a traditional front-opening bezel with a combination quartz time and tide clock movement. The easy-to-read dial displays a standard 12-hour clock that tracks time to the second while a fourth red hand indicates the current position of the tide. Constructed of a high luster, maintenance-free brass, this midsize porthole time and tide clock is guaranteed not to tarnish.
