No.

Water resistance is not a permanent characteristic and naturally decreases over time as sealing components age and wear.

Factors such as temperature changes, impacts, crown operation, chemical exposure, and normal aging of gaskets may gradually affect the performance of the sealing system.

For this reason, a watch that successfully met its water resistance specification when new may not provide the same level of protection indefinitely without periodic inspection and maintenance.

Regular servicing and pressure testing help ensure that water resistance continues to perform as intended throughout the life of the watch.
