Our solid brass Porthole Clock and Barometer are heavy brass castings, polished to a bright luster. The clock is a battery-powered quartz movement with both 12 and 24-hour markings on the brushed brass dial. The matching barometer (inset) reads in both inches of Hg and millibars, with an adjustable pointer to determine if the pressure is rising or falling. Both include screws for mounting to a plaque or wall. The clock is $210, the barometer is $240.
