Seiko G510 Technical Manual

Epd watch

PARTS CATALOGUE / TECHNICAL GUIDE

= Precautions

For G510 caliber watches, as they incorporate a microcapsule-type

electrophoresis display module and employ a special case structure, all repair,

adjustment, and replacement must be carried out in Japan, with the exception

of replacement of "Urethane Safety Catcher" or batteries.

Battery replacement can be done only at Seiko Service Centres where the

Water-Resistance Tester S-451A is equipped.

As soon as you receive a request from a customer, immediately contact the CS

Department.

1) Loosen and remove the four "battery cover screws" (#7500920).

* Use sufficient force as adhesive is used for preventing the screws from

loosening.

The other 6 screws should not be touched.

Pay attention not to damage or scratch the case and battery cover.

Use a short screwdriver because the case shape is unusual.

Avoid diagonally inserting a long screwdriver because this will cause

damage to the screw head.
