Friendly reminder
1. Any waterproof watch should not be worn in contact with hot water or water vapour (like hot baths, saunas, etc.)
2. Avoid using the watch in an environment where the temperature varies greatly. The temperature difference will cause the moisture in the air inside the watch to condense, thus causing water ingress and water fogging inside the watch.
3. If fogging occurs inside the watch, please go to a professional watch repair department for cleaning and maintenance as soon as possible.
4. After all, watches are precision instruments, so please use them with care. Good habits can increase the life of your watch, but bad habits can shorten the life of your watch.
