Horlogerie – Barometer
The barometer needs a check-up. At the moment I just openend it and will observe the pressure variations over the few next days. Today the QNH is 1017hPa.
The construction seems cheep: look at the chain, look at all the plastic! Could be a product from the East…
Compare the details of the chain with the last picture, an old barometer I use for instruction purpose: all metal, no plastic, a real watch chain, etc.
No wonder the plastic thingie gives only approximative information
