The accuracy of mechanical / automatic watches may not fall within the specified range of time accuracy because loss / gain changed due to the position of the watch, which is dependent on the conditions of use, such as the length of time during which the watch is worn on the wrist, arm movement, and whether the mainspring is wound up fully or not, etc.

Please go through the following checks, as your watch might be affected by nearby magnetism and temperature which may temporarily or lose time or stop operating:

Have you placed your watch at the following magnetic products that may affect your watch?

1. Cellular phone (speaker)
2. Bag with magnet buckle
3. AC-powered shaver
4. Portable radio (speaker)
5. Magnetic cooking device eg. Microwave oven, induction cooker
6. Magnetic health belt
7. Magnetic necklace
8. Magnetic health mat
9. Magnetic health pillow
10. Television
11. Staying near high voltage power lines 
12. any electrical products that emits magnetic field

Please keep the watch more than 10cm away from magnetic products.

Have you placed your watch at an extreme temperature area?

The parts that compose the accuracy of mechanical / automatic watches are made of metals. It is well known that metals expand or contract depending on temperatures due to metal properties. This exerts an effect on the accuracy of the watches. Mechanical / automatic watches tend to lose time at high temperatures while they tend to gain time at low temperatures.

In order to improve accuracy, it is important to regularly supply energy to the balance that controls the speed of the gears. The driving force of the mainspring the powers mechanical watches varies between when fully wound and immediately before it is unwound. As the mainspring unwinds, the force weakens.

Relatively steady accuracy can be obtained by wearing the watch on the wrist frequently for the self-winding type and winding up the mainspring fully everyday at a fixed time to move it regularly for the wind-up mechanical type.

Please go through the following checks, as your watch might be affected by nearby magnetism and temperature which may temporarily or lose time or stop operating:

A. Have you placed your watch at the following magnetic products that may affect your watch?

1. Cellular phone (speaker)
2. Bag with magnet buckle
3. AC-powered shaver
4. Portable radio (speaker)
5. Magnetic cooking device eg. Microwave oven
6. Magnetic health belt
7. Magnetic necklace
8. Magnetic health mat
9. Magnetic health pillow
10. Television
11. Staying near high voltage power lines 
12. any electrical products that emits magnetic field

Solution: Please keep the watch more than 10cm away from magnetic products. It may take some time to resume back to normal.

B. Have you dropped your watch, hit it against a hard surface or wore it while playing active / extreme sports that was exposed to strong vibrations?

Solution:

C: Have you left your watch in extremely high or low temperatures for a long time?

Solution: The watch will resume when the watch returns to normal temperature.

Yes, all automatic watches will make sounds because the rotors rotates (swings) at a very high rate of speed in the non-winding direction or "wobbling" when the rotor turns in the non-winding direction.

Some large automatic watches even amplifies a little.

An automatic mechanical watch comes with manual winding mechanism. When the watch is worn on the wrist, the mainspring is wound automatically through normal wrist movement. 

The watch can also be wound up by turning the crown. To do so, unscrew the crown (some watches do not require to unscrew the crown) by turning it counterclockwise.

To start the watch after it stops completely, wind it up either by turning the crown or swinging it from side to side until the second hand starts moving. Then, set the time and date before putting the watch on the wrist.

To wind up the watch, unscrew the crown by turning it counterclockwise, and then turn it clockwise slowly. The watch cannot be wound by turning the crown counterclockwise.

The watch is wound up fully. (Turning the crown further will not break the spring.) Once the watch is wound up fully, it operates for about 50 hours or indicated by your watch.

If the watch is used without being wound up fully, gain or loss of the watch may result. To avoid this, wear the watch for more than 10 hours a day. It the watch is used without wearing on the wrist; for example, if it is used on the desk like a clock, be sure to wind it up fully every day at a fixed time.

If you use a watch that has stopped with the mainspring unwound, winding the mainspring with the crown will not start the watch immediately. That is because the mainspring torque (force) is low at the beginning of its winding due to the characteristics of mechanical watches. The second hand starts to move when a certain degree of strong torque is reached after the mainspring has been wound up. However, swing the watch from side to side to forcibly turn the balance can start the watch sooner.
