The inside of glass is clouded. Why?

The inside of the glass may fog, such as when the watch is quenched, but the clock function will not be affected temporarily.

In summer, when the watch is exposed to cold air near the air outlet of an air conditioner, or when it comes in contact with cold air or snow in the outdoors from a warm room in winter, the temperature difference between the outside air and the inside of the watch may increase, causing the watch to take longer than usual.

If the haze does not disappear for a long time, moisture may have infiltrated into the product. Stop using the product immediately and contact the retailer from whom the product was purchased or the contact point for repair.
