When Does a Watch Need a Pressure Test?

Common mistakes to avoid

• Relying on an old result after impact or case opening.
• Assuming a rating never changes as seals age.
• Using a visibly damaged watch in water because it once passed.

If information is missing or contradictory, pause the purchase or use. A cautious answer based on the exact model is more useful than a confident guess.

A simple decision rule

Choose the option that meets your normal use with the fewest unsupported assumptions. Pay for features you understand and will use. For water exposure, repairs, battery replacement, pressure testing or movement problems, follow the manufacturer and use a qualified service professional.
