Seiko G510 Quick start 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.
11) Loosen and remove the four “battery cover screws” (#7500920).
* Use sufficient force as adhesive is used for preventing the screws from
loosening.
Pay attention not to damage or scratch the case and battery cover.
The other 6 screws should not be touched.
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.
