The American voyager windlass collection is a classic vintage design with an authentic nautical dial. The chrome windlass case represents an era of U.S. maritime history and craftsmanship. The quartz clock movement is highly accurate. Uses one aa battery with easy-to-adjust time settings. German-made hygrometer and thermometer movements display changes in temperature and humidity while the easy-to-read "comfort" scale shows current comfort levels when indicators cross on the dial. An adjustment setting in the back of the instrument allows easy user calibration. Features the patented Latitude Run® mounting system. Each instrument is protected by a mirror finish PVD coating and carries the exclusive lifetime M-M limited warranty. You can show off your Latitude Run® Time & Weather instruments pre-installed on our display plaque, handmade in the USA from North American hardwood. Perfect for your home, office, living room or den.
