Why has my mechanical watch stopped?

　　Mechanical watches are high-precision instruments that require careful handling to ensure optimal performance. Excessive impact must be minimised, and you should be particularly careful not to drop the watch onto hard surfaces. So, what are the common reasons for a mechanical watch to stop, and how should we address them?

　　Reasons for a mechanical watch stopping

　　Temperature may be a factor; if the mechanical watch is exposed to temperatures outside the normal range (below -10°C or above +60°C), the electronic components may function abnormally. The liquid crystal response time on digital watch displays may slow down in sub-zero temperatures and become dim in high heat, but will return to normal once the temperature is restored. Battery life is shortened at high temperatures (exceeding 40°C), which can even lead to internal battery leakage. Additionally, chemicals, gases, and mercury can cause discolouration of the case and strap. For example, mercury leaking from a broken thermometer can damage the gold plating on the case, leaving unsightly grey stains.

　　It is also possible that the battery has reached the end of its life and requires replacement. A watch battery's lifespan depends primarily on its capacity and the power consumption of the movement's circuit. The larger the battery capacity and the lower the circuit's power consumption, the longer the battery will last. Understanding your watch battery helps extend its life. If a mechanical watch stops due to the battery, note that battery capacity is measured in milliampere-hours (mAh); depending on the size, silver-oxide batteries generally range from a few to several dozen mAh. Watch circuit power consumption is in the microampere range, and current IC circuit technology can achieve approximately 1 microamperes.

　　Precautions for using a mechanical watch

　　1, avoid bringing the watch close to magnetic clasps

　　Regardless of the model or high value, Noob factory watches are vulnerable to magnetic fields. For mechanical watches, the movement is the most susceptible to magnetic interference; while quartz watches do not have as many steel components, they are still significantly affected. Regarding this issue, men in particular should note not to place their watches near belt buckles, while women should keep their watches away from magnetic clasps on handbags.

　　2, wearing the watch while bathing or swimming

　　Although some replica watches from the N-factory can be worn while diving, they are in the minority. Standard watches can be worn while washing, but they cannot withstand prolonged immersion. Therefore, please do not wear your watch while swimming or bathing, and certainly do not take it into a sauna; the high temperatures will cause the watch to oxidise.

　　3, never taking it to a professional service centre for maintenance.

　　Watches are items subject to wear and tear. To ensure a longer lifespan, they must be taken to after-sales service for professional maintenance and servicing. As for how often maintenance is required, please consult the after-sales staff.
