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

Butterfly Strap Adjusting Instruction

Instruction for Time Setting
1)
Pull the crown out to First position and turn the crown anti-clockwise until the
correct day of the week is achieved. The day and date will now be correct, now set
the time but make sure the time is set onto am or pm. Finally push the crown back
to the normal position.
Power Reserve Dial
This watch has a Power Reserve Indicator Dial to show amount of power remaining within the
movement. Wind the watch until the indicator hand on Power Reserve dial reaches the "40"
position, which means that it is now in full power. If the watch is not in use and Power Reserve
Indicator hand showing "40" position the watch will continue to function until the indicator
finally reaches "0". At this stage the power indicator needs to be rewound until it reaches "40"
position stage.

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
