CUSTOMER SERVICE STANDARD

This standard provides information on the minimum work to be undertaken for the following service procedure:

Water Resistance Testing

The water resistance test can be carried out by one of the following methods:

Test Procedure A: Air leak method
The watch is exposed to external pressure to verify case measured compression, resulting from overpressure.

Test Procedure B: Immersion method - Overpressure
The watch is exposed to water and pressure in a controlled environment. Observations are made of any air bubbles arising from the watch.

_______________Immersion method - Vacuum
The watch is placed in water and then pressure is reduced - Air will be seen leaving the case through any leakage areas.

Servicing the Watch Case:
1. If the leakage point has been identified in testing a part procedure may be applicable -
2. Original replacement parts to be used if possible - customer to be advised before any non standard replacement parts are fitted.

Procedure:
Open watch case - inspect case seals and contact surfaces for -
Service crown and pendant
Servicing pushers
Back case/case apertures
Glass sealing

Supplementary Testing:
After servicing, the watch case should be re-tested, where a case has been tested without the movement a further test should be carried out after the watch is assembled.

Delivery:
- Where any parts are replaced the old or original parts should be returned to the customer.
- At the time of delivery the customer is advised of the performance of the watch during testing and of any operational considerations (locking crown/ ensuring conventional crown is against case etc.,)
- Customer is advised of need to rinse case after immersion/exposure to salt water.
- Customer advised of the effect of extreme temperature prior to use immersion.

NB: An inspection report will be provided on any defects, which may impair the performance of the watch. The Watchmaker may elect NOT to undertake the service if work can not be completed to WCA Standards or for water resistant watch cases which cannot be made water resistant. Customers may elect not to have water resistance test carried out on a watch, however the customer will be required to sign an indemnity. The customer (or his/her agent) to retain a copy.
