1 Case back
· To fix the case back to the case, the case back itself is screwed into the case, or the case back screws
are used, depending on models.
· For the models using the case back screws, use the adhesive “LOCTITE 241” to prevent them from
loosening.

I. REMARKS ON DISASSEMBLING AND REASSEMBLING
For conventional type
Note: Never use an adhesive other than “LOCTITE 241” for fixing the case back screws.
• How to fix the case back with the case back screws and the adhesive
1. Wipe any adhesive, oil, dust or dirt off the screws and the
holes for screws on the case with alcohol.
2. Before setting the case back to the case, apply a proper
amount of the adhesive to the holes for screws as shown
at right.
3. Set the case back to the case and then, tighten the case
back screws firmly.
* Tighten the screws one by one in diagonal direction.
* After tightening once, give the screws another turn to
fix them securely.
4. Leave the watch untouched at room temperature for
about one day until the adhesive is completely hardened.
Notes:
* Apply only a necessary amount of adhesive to the hole lest it should come out on the case.
* Take care not to let the adhesive stick to the inner surface of the case.
