This weather station makes an excellent gift. It includes a brass nautical tide clock (quartz movement), aneroid barometer and a thermometer/hygrometer mounted on a wooden base with a mahogany finish. The instrument bases are constructed of brass and the opening ports are made from a high quality alloy, polished by hand. This finish will stand up to even the harshest of conditions without ever tarnishing or discoloring. The bases of the instruments measure 4.75", with 3" dials.
