I have a pair of Weems and Plath instruments that are solid brass. Mine are roughly 3-1/2" dia. face, somewhat on the small size. From time to time I repolish and lacquer. That lasts for 5 or 6 years. The Barometer is surprisingly accurate, usually within a millibar or so with the local weather
station. The clock recently had to have the quartz movement replaced due to a leaking battery
. The movement is either Swiss or German (can't recall) and keeps typical quartz accurate time. These are rather old -at least twenty years - and look great, work great. At home I have a Chelsea Ship's clock, 6 or 7 inch face, also solid brass and with a quartz movement. Can't beat modern convenience of not winding
That said, my favorite barometer, no longer manufactured, had a 24 hour digital bar graph recording of pressure, in addition to the direct readout. This was the most useful. An historical view of barometric pressure is what helps to determine weather
, not the immediate pressure. The hour by hour past measurements provide the trending data. Unless you are willing and able to record
by hand the movement of the barometer's needle you would be better served by a recording type barometer.
Get the analog type for ambiance, digital for utility.
P.S. Weems and Plath still carry replacement parts
for these instruments. That's where I got a replacement movement. My failed digital barograph, when the digital screen
failed, could not be repaired and was tossed.
