How much do you know about your own automatic mechanical watch?
Each of us likes to decorate ourselves with accessories, and watches are no exception. Now people wear watches more as a kind of decoration. But watches have the function of time calculation after all. How to make your automatic mechanical watch work normally seems to require you to know more about your automatic mechanical watch.
1. About the error of automatic mechanical watch
The allowable error range of mechanical watches is ±30 seconds/day, and the average error range of movements certified by the Observatory is between -4 seconds/day and +6 seconds/day. The specific error depends on the movement used by the watch. Not according to the principle that the higher the price, the smaller the error. The power source of the automatic mechanical watch is the swing of the wearer’s wrist to generate energy to wind the mainspring. A fully wound automatic mechanical watch can continue to run for about 36 hours. If it is guaranteed to be worn normally every day Under normal circumstances, it can be operated for about 15 hours. If it is not worn for more than the above time or the swing is insufficient (the wearer has less exercise), the watch will stop. Before wearing it again, the watch should be fully wound.
2. Why do automatic mechanical watches stop?
First of all, we will introduce what is a fully automatic mechanical watch, which is operated by the automatic winding mechanism that can be wound up by rotating the automatic rotor in any direction (visible on the transparent bottom cover watch). It is conceivable that as long as the watch is worn on the hand, as the arm moves, the automatic rotor will also rotate to generate energy. Generally, a fully automatic watch should be worn on the hand for more than 8 hours a day to replenish the energy of the mainspring, but it is not absolute. It is recommended to wear a watch during the holidays. Only when it is worn on the hand to continuously replenish energy for the mainspring, the watch will not stop. Nowadays, it is common for people who work in the office that the watch often stops. In addition to the cause of the movement, it is because the wearer does not exercise enough and cannot add enough energy to the mainspring. If this is the reason, you can use the manual dial A clockwork method to make up.
3. Do you usually wind up the automatic watch?
The automatic watch is based on the general manual winding watch plus an automatic part. The automatic part includes the automatic rotor and the automatic wheel. The automatic watch we sell is generally in a stopped state when it comes out of the cabinet. First, the salesperson needs to help the customer to open it After that, as long as the customer wears it for enough time every day, the automatic rotor can replenish energy for the mainspring so that the automatic watch can run normally. It is necessary to drive many automatic wheels to rotate together with the handle, and the automatic parts are very easy to wear and tear, which will increase unnecessary maintenance costs for customers.
4. Why do hand-wound watches have larger errors than ordinary automatic watches?
Now the high-end automatic watches on the market (like Rolex, Omega, etc.) have been certified by the Observatory, and the average error range of the movement is required to be between -4 seconds/day and +6 seconds/day when it leaves the factory. On the contrary, various famous watch manufacturers focus on the materials used in the requirements of hand-wound watches, which are generally precious metals; the thickness of the watch is designed to be very thin. Watch manufacturers believe that the consumers of famous watches are mostly specific groups of people who often own several watches and wear different styles of watches according to the occasion. Such famous watches made of precious metals are usually regarded as banquet watches. Wearing this kind of watch is mainly a symbol of status. The watch itself does not pay much attention to its accuracy, so it is mostly a two-hand watch or even does not have Water resistance.
