Water Resistant Performance; Magnetic Resistant Performance - Seiko C-26 Instructions Manual

* Overcharge prevention function
When the secondary battery is fully charged, the overcharge prevention function is automatically
activated to avoid further charging.
There is no need to worry about damage caused by overcharging no matter how much the
secondary battery is charged in excess of the "time required for fully charging the watch."
* For the required time to fully charge the battery, see "Guide to charging times" → P.37.
■ Notes on charging the watch
• When charging the watch, do not place the watch in close proximity to an intense light
source such as lighting equipment for photography, spotlights or incandescent lights,
as the watch may be excessively heated resulting in damage to its internal parts.

• When charging the watch by exposure to direct sunlight, avoid places that easily reach
high temperatures, such as a car dashboard.
• Always keep the watch temperature under 60°C.

Magnetic resistant performance

Affected by nearby magnetism,
a watch may temporarily gain or lose time or stop operating.
* When the hand positions deviate to display incorrect time as a result of influence of magnetism, this watch
automatically corrects the hand alignment itself. (P.66)
Indication on the case back
No indication Keep the watch more than 10 cm away from magnetic products.
Keep the watch more than 5 cm away from magnetic products.
6
Keep the watch more than 1 cm away from magnetic products.
If the watch becomes magnetized and its accuracy deteriorates to an extent exceeding the specified rate
under normal use, the watch needs to be demagnetized. In this case, you will be charged for
demagnetization and accuracy readjustment even if it happens within the guarantee period.
The reason why a watch is affected by magnetism
The built-in motor is provided with a magnet, which may be influenced by a strong external magnetic field.
