CLEANING
Use a soft, clean cloth to wipe off any moisture that adheres to the case or band. Made of high-grade stainless
steel, the band will become soiled with dust and perspiration due to contact with skin. Failure to keep the watch
and case clean may result in a skin rash.
COMPOSITION

Crystal ..................................................................................................................Sapphire with Anti-Reflective Coating
SAFEGUARDING
WATER EXPOSURE
Rated at 10-bar hydrophobic, the timepiece may be worn during bathing, swimming and shallow diving. It is not
designed for scuba or saturation diving. Before exposing the timepiece to moisture, be sure both crowns are pushed
in fully against the casing. Do not pull out either crown or push any button if the timepiece is wet. If used in
seawater, rinse the timepiece with fresh water and dry completely.
TEMPERATURE
For precision timekeeping, normal operating temperature is -10°C to 60°C (14°F to 140°F).
MAGNETISM
Strong magnetic fields can have an adverse affect on the timepiece. Keep it away from magnetic objects.
CHEMICALS
The timepiece may become discolored or damaged if exposed to cosmetic spray, detergents, adhesives, solvents, or
paints.
SPECIFICATIONS
Frequency of crystal oscillator ......................................................................................................32,768 cycles per sec.
Drive System......................................................................................................................Step motor (quad component)
Accuracy at normal temperature ............................................................+/- 15 sec./mo. @ 5ºC TO 35ºC (41ºF TO 95ºF)
Operating temperature range............................................................................................-10ºC to +60ºC (14ºF to 140ºF)
Water resistance ........................................................................................................................................10 bar (100m)
Battery ....................................................................................................................................................Lithium SR927W
Battery life..........................................................................................................................................Approx. two years*
*Battery life varies according to usage. See “LOW BATTERY INDICATOR” for more information about the battery.
SHOCK WAVE
Although the timepiece resists shock damage, impact against hard surfaces may cause damage.
PERIODIC MAINTENANCE
To ensure that the chassis, crown, crystal seal and gasket remain resistant to water exposure, it is recommended
that the timepiece be inspected once every two to three years by an Authorized Oakley Service Center.
