The First Light cabin collection is a versatile design that goes well with any decor, indoors or out. A clean and crisp white dial makes first light the right choice in a variety of settings. The cabin collection features a 0.7mm thick polished stainless steel case with a durable plated finish. The quartz clock movement is highly accurate. Uses one aa battery with easy-to-adjust time settings. German-made hygrometers 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 master-mariner mounting system. Each instrument is protected with a mirror finish pvd coating and carries the exclusive lifetime m-m limited warranty. You can show off your Master-Mariner 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.
