<Replacement of Rechargeable Cell>
• This watch utilizes a special rechargeable cell that does not require regular replacement.
However power consumption may increase after using the watch for a number of years due to wear of internal
components and deterioration of oils. This may cause stored power to be depleted at a faster rate. For optimal
performance, we recommend having your watch inspected (chargeable to the owner) by an Authorized Service
center to ensure operation is within factory specifications.
WARNING
• The rechargeable cell should never be removed from the watch.
If for any reason it becomes necessary to remove the rechargeable cell from the watch, keep out of the reach of
children to prevent accidental swallowing.
If the rechargeable cell is accidentally swallowed, consult a doctor immediately.
• Do not dispose of the rechargeable cell with ordinary garbage. Please follow the instructions of your municipality
regarding collection of batteries to prevent the risk of fire or environmental contamination.
WARNING
• Never use a battery other than the rechargeable cell specified for use in this watch.
Although the watch structure is designed so that it will not operate when another type of battery is installed, if a silver
battery or other type of battery is installed in the watch and the watch is recharged, there is the risk of overcharging
which may cause the battery to rupture. This can cause damage to the watch and injury to the wearer. When replacing
the rechargeable cell, always make sure to use the designated rechargeable cell.
