The frequency of pressure testing depends on how the watch is used.

As a general guideline, we recommend considering a pressure test:

• Every 1-2 years for watches frequently exposed to water
• Before holidays involving swimming, diving, or extended water activities
• After any significant impact to the watch
• After any service requiring the case to be opened
• Whenever there is concern regarding water resistance performance

For watches that rarely come into contact with water, testing may be required less frequently.
