i have an automatic watch,
Welcome to the club. :-)
it gain 20second a day
Depending on the type of movement and its age, you may consider that an OK value. The first and most important thing you need to understand and accept is that no mechanical watch in the world can do even half as well as any cheap-cheaper-cheapest quartz watch in terms of time-keeping. Any $5 Walmart quartz will easily outperform even the most expensive Rolex, Patek Philippe, JaegerLeCoultre, IWC, Omega, Breitling, ... when it comes to time-keeping. Full stop! (US: Period! :-)
And now let's have a look at what "good time-keeping" means in the world of mechanical watches:
Even very good chronometer movements usually lose or gain on the wrist within the often quoted -4 to +6 seconds/day off real time. A run-of-the-mill non-chronometer ETA movement is considered good if it stays below +10 seconds/day off real time; Seiko and Miyota movements are considered still acceptable for anything up to +20 seconds/day.
Although the values quoted above are for out-of-the-box watches fresh from the factory, I'd like to say that I have a 14-year old Seiko 5 that gains about half a minute/day, and my watchmaker said that it was doing all right for a watch of that age, particularly when considering that the watch had never been serviced since the day of purchase. (Mind you, any other watch than the good old Seiko 5 would have quit long ago.)
Usually, mechanical movements need to be "broken in" by wearing them regularly or non-stop. After a couple of weeks, sometimes months, they begin to show their longterm performance.
And as always, just when you've got used to it, after a couple of years or so, it's time to turn them in to a watchmaker for a service (cleaning, lubricating, regulating) in order to keep them going - unless you have a Sekio 5 (see above :-).
it is an over-wound watch??
Definitely not, as it is technically impossible to overwind an automatic movement whilst wearing the watch on your wrist, and even when you try to wind the movement by using the crown. (Note that winding a Seiko automatic by the crown is usually impossible.) *All* automatics have slip clutches that prevent overwinding and let the rotor spin at idle when the main spring is fully wound.
how can i fix this problem?? how to prevent over-wound besides over winding?
As there is no overwinding problem, you needn't take any special precautions. If you think that the watch gains too much, you may go to a qualified watchmaker and ask him/her what can be done. Although regulating the movement might by an option, don't expect such "tuning" to work miracles. No watchmaker in the world can make a run-of-the-mill mechanical movement work phenomenanlly better than before, not even when using a timing machine.
HTH and best regards, OP .
