What is a one-sentence summary of the following article?
Mechanical watches need to be wound by hand periodically to ensure that the mechanical parts are being given enough kinetic energy to stay in motion and keep time accurately. Rolex technicians recommend winding their watches about 20 rotations once a month or so; if you’re using a knock-off, the watch will probably lose time faster and you might need to wind it more frequently.  To wind a Rolex-style watch, unscrew and release the crown until it is in the first position. Don’t pull it out any further. The crown will then be ready to rotated, winding the watch’s mechanical innards. Wind the crown stem until you start to feel resistance, then push the crown back into place and screw to secure it.  Wind your watch every few days to keep it from losing time. As a rule, the more you wear your watch, the better time it keeps. The kinetic energy generated by wearing the watch on your wrist as it moves is transferred to the watch to keep the gears running. Make sure your watch is getting plenty of wear, or you may find that it is becoming less accurate. If you’re not in the habit of wearing a watch, or are for some reason unable to, consider purchasing a watch-winder. Watch-winders are small devices that rotate your unworn watch continuously, mimicking natural motion. Leaving your watch on a watch-winder when you’re not wearing it can prevent it from losing time as quickly. Watches, like cars and other mechanical appliances, require regular service. Take your Rolex replica to a watch specialist once or twice a year to have it inspected for mechanical flaws. A watch specialist can alter and replace springs, repair broken gears and keep the watch running like new.  Watchmakers and specialists can usually identify tough to explain mechanical problems that might cause your watch to run poorly or stop altogether. Certain mechanical parts may wear out faster on replica models. It might be a good idea to get these parts replaced every so often. Replica Rolexes, while fine watches in their own right, are not made to quite the same specifications as the real thing, and as a result are more easily upset or damaged. Try not to expose your watch to excess moisture, and be careful about dropping it or allowing it to absorb impact. Even if these things don’t break your watch outright, they may hinder the internal mechanics enough to render it unusable.  Mechanical watches are also susceptible to changes in gravity, polar positioning and magnetism. They require greater care and upkeep than digital and satellite watches.  If you’re planning any sort of dirty or physical activity, it may be best to leave your Rolex replica behind. These watches were designed more for casual wear, and while they may be more capable of withstanding a moderate amount of punishment, it’s better not to take chances.

Summary:
Wind it regularly. Wear it more often. Get it serviced as needed. Avoid exposing it to harsh conditions.
