Atlantis Quartz Movement Ship's Bell Clock by Weems & Plath. These clocks have been used on Navy ships for decades. Our clock has the convenience of battery operated quartz accuracy combined with the authenticity of a striking ship's bell. The ship's bell clock is one of our most popular nautical decor items as well as one of our most popular nautical gifts. The case is heavy solid brass with a beveled glass lens. It can be wall mounted using the included brass screws or it can be mounted in the optional mahogany cradle. The bell chimes one through eight bells every half hour indicating the watch change and it can be silenced if you choose. This is also available in an eight-day wind version. Our quartz ship's bell clock comes with a two-year warranty. AA Battery included.
