How often should a mechanical watch be serviced?

　　As precision timepieces and decorative items, mechanical watches must combine practicality with style. So what do we need to look out for when buying a mechanical watch? Today, Xiaoya shares some insights on purchasing mechanical watches for your reference.

　　Mechanical Watch Service Intervals

　　For standard watches, 3-5 years is acceptable. Whether it should be 3 years or 5 years can be determined as follows: within 3 years, leave it alone; at the 3-year mark, pay attention to the daily rate variance. It is best to record the daily variance continuously for a week, calculate the average, and log it down. For example, if it gains an average of 12 seconds per day, once the variance shifts to gaining an average of about 7 seconds per day—meaning it has slowed down by an average of 5 seconds—it is time to send it for cleaning and oiling.

　　Certain watch brands and technologies can extend the service interval. For instance, Omega's Co-Axial technology and Rolex's sealing technology ensure proper operation over long periods, meaning Co-Axial Omegas and Rolexs can comfortably go 10 years between services. Arlanch's anchor escapement requires no lubricating oil, as it is crafted from a high-carbon alloy that uses the carbon within the alloy for self-lubrication. If your watch is a chronometer, it must be returned to official after-sales service for maintenance; otherwise, the chronometer certification will effectively lapse.

　　Mechanical watch maintenance tips

　　1, Daily winding

　　For manual-winding mechanical watches, it is recommended to wind them 20 to 30 times before first use, and it is best to wind them regularly every day thereafter. Automatic mechanical watches rely primarily on arm movement for winding; if the power reserve is insufficient, you can supplement it with manual winding. Generally, well-designed mechanical watches feature a slipping clutch mechanism to prevent the mainspring from being overwound and snapping. Therefore, the mainspring will not be fully wound even after 1 days of rotation.

　　2, Keep away from magnetic fields

　　Among everyday appliances, microwaves, irons, fax machines, electric shavers, vacuum cleaners, and even the mobile phones and computers we use daily can cause a watch to become magnetised to some extent. Isn't that alarming?

　　It is necessary to be mindful of magnetism, especially when you are frequently exposed to it. For example, wearing your watch while shaving at home or using a vacuum cleaner, or the magnetic clasps found on some women's handbags—these all generate relatively strong magnetic fields that can, to varying degrees, affect timekeeping.

　　3, Water resistance

　　Any mechanical watch marketed as water-resistant, anti-magnetic, or shock-resistant should not be worn during hot showers, car washes, dishwashing, or in hot springs! High temperatures, hot water, soapy water, and chemical detergents can cause the waterproof gaskets to age and deform, or lead to condensation inside the watch, resulting in chronic damage. Furthermore, never pull out the crown while the watch is submerged, as water will enter the watch directly.
