TIPS:：All dimensions are measured manually，there is a reasonable error，Everyting in kind prevail.

Importance:

1.The travel time error range of automatic mechanical watches is: -50 ~ +90 seconds per 24 hours

2.How to use a mechanical watch: A fully automatic mechanical watch requires the user to insist on wearing it normally every day and have an appropriate amount of activity, so that it can continue to be wound, maintain power, and operate normally. It is normal to walk slowly when the wearer is less active. When using for the first time, please rotate the crown 20-30 times to wind the mainspring initially.

Abnormal s

Turn the clockwork:

The energy in the new mechanical watch is almost zero. Please wear enough momentum for the first time.

The winding of the mechanical watch is manual and automatic. According to the actual situation of the movement

 

Stainless steel wear:

Stainless steel is resistant to bumps but not wearable. It is easy to see small scratches. Especially high-gloss mirror products,

When you wear it, you should pay attention to it.

 

Water protection:

Any watch should not be worn in warm water or in a bathroom,even if your watch is a waterproof watch,

Because the seal rubber of the watch is susceptible to heat,

And after the thermal expansion, the sealing property is lowered, the surrounding water vapor molecules are relatively small and can easily penetrate into the case，so it will cause damage to internal machinery.

 

Antimagnetic:

Mechanical watches should pay attention to anti-magnetic, do not touch with strong magnetic objects such as mobile phones and magnets.

If you find that the watch is going fast. Mostly because of the magnetic field, You can eliminate the magnetic field through the instrument

 

Error:

The error of the mechanical watch is normal within 1 minute under normal conditions.

If the error is found to be large, check if there is enough power.

 

Adjust the calendar: the time between 22 and 2 o'clock is mechanically adjusted. Please do not adjust the human intervention at this stage.
