What causes DW watch dials to discolour?

　　If the dial of a newly purchased DW watch discolours, you must ensure you deal with it promptly. Therefore,DW watcheswhat are the general causes of dial discolouration? Let us explore this topic together.

　　Causes of discolouration in DW watch dials

　　Cause one: A DW watch left or exposed to sunlight for a long period; various rays in sunlight gradually discolour everything, and delicate items are no exception, escaping no one.

　　Cause two: Water ingress or prolonged dampness in a DW watch. Poor sealing of the DW watch case allows external moisture and vapour to enter the watch, which easily triggers dial discolouration or peeling of the dial clear coat, characteristically occurring frequently around the edge of the dial.

　　Cause three: DW watches stored and left unused for long periods with luminous hands. This depends on the nature of the material chosen for the luminescence. Extra caution is generally required for older DW watches, where discolouration often appears precisely at the positions corresponding to the luminous hour and minute hands.

　　Cause four: Exposure of a DW watch to radiation or radioactive substances. Radiation is used in medical treatments and certain industrial processes, and it is the most potent, capable of discolouring items in a very short time. Someone once went to a metal research and testing department to test the gold plating thickness of a DW watch case; the equipment they used had intense radiation. As soon as the experiment ended and the case was taken out and looked at, disaster! The previously colourless watch crystal had turned brown, and the depth was uneven, resembling a mottled glass. In the jewellery industry, radiation is used to alter the colour of certain gemstones, such as topaz, and pearl colour alteration is done similarly. If you are a patient undergoing radiotherapy or examinations involving radiation, never wear your DW watch to the hospital.

　　DW watch care methods

　　1, It is best to place desiccant where the watch is stored, but avoid using chemicals such as mothballs and insect repellents.

　　2, Leather watch straps should avoid contact with water as much as possible to prevent the strap from hardening, developing odours, and consequently breaking.

　　3, If the watch shows any abnormalities, it should be immediately taken to a nearby specialist watch shop for inspection.

　　4, Automatic watches must be kept under conditions of sufficient physical activity, meaning they must be worn for more than 10 hours daily.

　　5 Different occasions require different watches; for example, it is best to choose a sports watch with excellent water resistance and shock resistance when exercising.

　　6 Because each watch has a different internal mechanical construction, under normal usage conditions, the variance for a mechanical or automatic watch is within 30 seconds per day, whereas quartz watches exhibit lower variance and greater accuracy.

　　Conclusion: If dial discolouration occurs on a DW watch, it must be handled properly and promptly, otherwise the discolouration will become increasingly severe and affect the aesthetics of the watch.
