Automatic Movement Operation Manual
Automatic watches can be used only by those who are reasonably active as the automatic
winding relies on a regular movement of the wrist. The watch must be given an initial manual
wind of 8 to 10 turns and provided that it is worn on the wrist for a minimum of 8 hours each
day it will continue to function indefinitely and may be taken off the wrist for a maximum period
of 30 hours. If this period is exceeded the movement will stop and another manual wind will be
necessary. It must be remembered that when worn in bed the movement of the wrist is
insufficient to operate the automatic winding.
Time Stand Accuracy
1) 21,600 beats per hours
2) Accuracy between -30 to +30 seconds per day worn under normal conditions.
Butterfly Strap Adjusting Instruction
Firstly, open the butterfly buckle and then pull out the pin. Adjust the strap to the required
length, and then push back the pin into the correct hole. Finally, close the butterfly buckle until
it clicks into place.

Water resistance is not permanent. In the course of time, the gaskets of the case and
crown may become worn and reduce the water resistance of your watch. We recommend
the periodic checking
Normal Crown – always make sure it is pushed fully into case
Screw down Crown – tighten screw down crown completely to screw lock position.
To maintain water –resistance crystal, crown and case must remain intact
Exposure to Salt Water
If your watch is designed for sports or working in the water and it becomes exposed to salt
water or significant amounts of perspiration, it should be rinsed in fresh water and dried
thoroughly with a soft dry cloth.
Important
Buttons must not be operated while in contact with water
