First, the brand name watches worn every day, can also be said to be brand-name watches 365 days without leaving, if you find a large error of the brand-name watches, or brand-name watches into the water, it is best to repair and maintenance; if your brand-name watches everything Normal, preferably three to five years of maintenance time; some brand-name watches do not leave, a wear that is more than 10 years, this is not to be brand-name watches, because of prolonged use, brand-name watches, the oil will be lost or dried, Under the conditions of oil loss, will accelerate the wear and tear of the shaft; in the air there is our invisible quartz particles, will be attached to the oil, if not maintenance for a long time, let the brand watches keep walking, will only accelerate the shaft Axis wear; some people wear is 10 years, 20 years, brand-name watches will go, never want to maintain, until the failure, many parts have been severely worn, after maintenance, its accuracy will be greatly reduced, not as good as the new brand-name watches . Second, if you do not wear, an average of less than twice a month, it is recommended 5 years or 10 years is best repair. The best two years every three years to be a thorough cleaning, maintenance (last oil). Mechanical watches can usually be divided into the following two kinds: manual refining and automatic winding watch (AUTOMATIC) two. Both mechanical power sources are powered by the clockwork within the movement, driving gears and then promote the hands, but the power source in different ways. Mechanical hand refining is by manual on the mechanical watch, the thickness of the movement than the average automatic watch some thinner, the relative weight of the entire watch is lighter. The self-winding watch, is the use of movement at the bottom of the automatic disk around the pass and the resulting power to drive the clockwork to produce energy, but the relative thickness of the watch than the average hand watch thicker. Mechanical watch has the advantage of: through regular maintenance wash oil, can be used for a long time; but the disadvantage is: the error is larger than the quartz watch , due to the quality of the production of high and low and the internal movement of the watch vulnerable to gravity impact Produced error. The error of a mechanical watch is usually calculated by the number of seconds per day, while the error of a quartz watch is calculated by how many seconds per month. Mechanical watch repair the most common situation, nothing more than water and collision. Unless marked with a mechanical watch waterproof function, or to avoid case water, because the water will cause mechanical corrosion, destructive power. Sea water is even more untouchable. Even if the waterproof watch, only one year of waterproof protection, because the table waterproof ring after a year of wear and tear, plus sweat, dust and other inevitable external factors, will be tired, so a year later Must be new waterproof ring, or that is not waterproof. Waterproof, but also to prevent collision. To the extent permitted by the economic power, there may be two or three watches that can be replaced in daily life: wearing a mechanical watch while in static motion and wearing a long sleeve while working in a leisurely fashion so that the service life of the watch can be extended . Mechanical watch is driven by mechanical gears and clockwork, rotation inevitably produce friction, so the course of time must be refueling, lubrication, to reduce the wear rate of parts. Otherwise, it will be very serious for the problem to be repaired after it is out of order. Therefore, "regular inspection" is very important; and every three years, a thorough cleaning and maintenance is required. Mechanical automatic table using three to five years maintenance cleaning time is appropriate, good table is also true. Some people wear a few years, that as long as the watch will go do not manage it, and other problems, will take it to repair. In fact, this is not good. In short, treat the watch as the same as the car, pay attention to maintenance.
