Mechanical watch can be divided into two kinds: manual watch and automatic watch. The power sources of these two machines are driven by the spring in the machine core, which drives the gears and then pushes the needle, but the ways of power sources are different. Then will the mechanical watch not go without it?
Mechanical watches don't go normally without them at night. If automatic watches want to keep walking, they must be moved. Even if it moves slightly for a while, it can walk without it, just by turning the clockwork on the crown.
After 12 hours of continuous walking, the clocks in the watches are usually tightened. Therefore, when it is removed from the wrist and placed in a static state, the watch machine should be able to maintain its walking ability for more than 12 hours. But this means that under normal wearing conditions, if individual users are basically inactive or less active, the table can not meet the above standards. Therefore, in this case, when the watch is taken down and placed, it should be swing several times; or, like ordinary watches, it should be winded several times by hand so that when the automatic mechanical watch is placed, it can also run normally.
No timing is allowed between 10 p.m. and 2 a.m. After the watch is adjusted, the handle must be pushed back to the bottom. According to the national standard, the travel time error of mechanical watches (including fully automatic mechanical watches) should be controlled within 45 seconds. Fully automatic mechanical meter requires users to wear it regularly every day and have appropriate amount of activity in order to keep it on top, maintain power and operate normally. It is a normal phenomenon that the wearer may travel slowly when he has a small amount of activity. When using for the first time, please rotate the handle head 20-30 times to make the clockwork initial chord.
