Cleaning the watch helps to maintain its original luster and rinses away any corrosive deposits that may damage them over time
Just as different materials require different cleaning agents, how often you should clean your watch strap depends on how often and where you wear it.
If you wear the same watch every day and you sweat a lot, clean it every two to three weeks.
If you change your watches frequently and often wear them to do office work, you can wash them a few times less-once every three to four months.
To clean your case(watch body), remove all belts that may be damaged by liquids. Then, rinse the shell with soapy water. Use a gentle brush to remove dirt from small corners. Pat dry with a soft cloth or old T-shirt, and then air dry.
Leather is perhaps the trickiest material to clean, in general it shouldn’t get wet. Moisture can stain the leather and cause it to dry out and deteriorate over time
When cleaning the leather strap, remove the strap from the case, and then wipe off the debris with a clean cloth. If the strap does get wet, dry it immediately with a clean cloth or towel. This includes sweat, which leaves corrosive stains and may damage the strap. In other words, wearing a leather strap in an active environment is not a good idea.
Massage the conditioner into the leather with a soft cloth to remove dirt and deposits and soften the leather. Wipe clean with a towel. Let the belt dry-overnight if possible. Then, fasten the belt again and enjoy the soft feel without any fashionable smell.
