I. About Automatic Mechanic Watch A mechanic watch uses a mechanical mechanism to measure the passage of time, as opposed to modern quartz watches which function electronically. It is driven by a spring (called a mainspring) which must be wound periodically. An automatic wind watch is a watch that powered by the swinging of your arms to keep the watch ticking. If you do not wear an automatic watch consistently (for about 8 to 12 hours a day), you can keep the watch powered with a watch winder. II.

Attention when setting an Automatic Mechanic Watch Note One: Do not set the date and day between 9:00p.m. and 5:00 a.m. otherwise, the date may not change properly and bring damage to your watch. if it is necessary to set the date during that time period, first change the time to any time outside this period, then set the date. Note Two: While setting the time, be sure to check that the correct A.m. or P.M. period is set. (the date will be changed automatically once every 24 hours.) 1. The mechanism of the mechanical watch is different from that of a quartz watch. To set the time accurately, first turn the minute hand 4 to 5 minutes behind of the desired time and then advance it to the correct time. 2. If you only have to adjust the time, pull out the crown direct to position 2. 3. Push the crown back in to position 1.
