MECHANICAL WATCH (NO BATTERY)
Mechanical watches differ from Quartz watches in several respects:
1. No battery changes are needed – they are powered by a main spring, which is wound either by wrist movement; or, in some models, by daily winding of the setting crown.
2. Because it is a mechanical device, its accuracy is subject to the effects of gravity and temperature. You can expect, on the average, a daily variance of up to -30 to +50 seconds for mechanical watches.
3. With over 100 working parts, cleaning and lubrication are recommended every three to five years for optimum accuracy and long-term efficiency.
THE AUTOMATIC SELF-WINDING MECHANICAL WATCH
The Automatic mechanical watch is self-winding once it is running. To start the watch, it must be wound at least six or seven times before you wear it. After that, your daily activity should wind the watch sufficiently to keep it running at night when it is not worn. If normal daily activity is not sufficient to wind the watch automatically, manual winding may be necessary.
AUTOMATIC WINDING STRUCTURE
Winding direction : Counter-clockwise (seeing from case back side)
WINDING THE MAINSPRING
Automatic winding watch can also be hand winded by turning the crown in “A” position. Wind 15～20 times clockwise until second hand starts to move naturally.
ADJUSTMENT OF THE TIME
Step 1. Pull the crown out to the Position “B”.
Step 2. Turn the crown to set hour and minute hands.
Step 3. After the time has been set, push the crown back to the Normal position “A”.
IMPORTANT: in order to keep your watch water resistant, and after any adjustment, always push the crown back in to the normal position “A”.
