2. WORLD TIME FUNCTION

The basic movement structures of Cal. 5T82A is similar to the previous Cal. 7T Series watches,

and the knowledge and technique you have gained in handling the previous Cal. 7T Series

watches will come in handy when you repair Cal. 5T82A.

When repairing, however, you are requested to have the full knowledge of the features character-

istic of these watches and strictly observe the repairing and checking instructions provided in this

guide so that the watches will be repaired correctly.

I. FEATURES

As Cal. 5T82A has new movement structures, the operating procedures for ALARM setting, time

setting, and ALARM hand position adjustment differ from those of the previous Cal. 7T Series

watches.

As a result of this structure change, the battery life of Cal. 5T82A has increased to 3 years as com-

pared with that of the previous Cal. 7T series watches.

•The ALARM sounds only once at a designated time within the coming 12 hours and it is

automatically disengaged.

•Pushing the crown back into the normal position after setting the ALARM will prevent

the set ALARM time from changing by an accidental pressing of the button.

1. ALARM FUNCTION

• Apart from the main time, the time in the city selected by the city hand is displayed with

the designated WORLD TIME hands.

•The time in 24 cities is displayed in the 24-hour indication.
