Mechanical Movement Operation Manual
A Mechanical watch is a device for keeping time, which uses the energy from a wound spring,
and keeps time through the highly regulated release of that energy through a set of gears (the
wheel train) and an escapement. It differs from typical quartz watch in that it uses purely
mechanical components to keep time. Mechanical watches typically can run for about 40
hours on one full winding of the mainspring.
Important
Over wind of the spring may cause damage to the mainspring. Only wind the spring as
far as it will go but not beyond.
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
