Calibre 417 
 
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.

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
