Accuracy will vary depending on the temperature. A piece of metal of about 0.1 mm, as thin as a hair, is wound That is the key that controls the accuracy of all mechanical watches In other words, When it is hot, the hairspring expands and the watch tends to lose When it is cold, the hairspring contracts and the watch tends to gain This is typical <> Hairspring For lifelong use of your mechanical watch rule No.5 Do not give your mechanical watch a strong shock.
