Things you must know after buying a mechanical watch

Daily Precautions for Mechanical Watches

• Do not use the watch (including waterproof watches) in hot baths, saunas, or environments with large temperature changes.
• Do not operate the watch's buttons and adjust the crown in water.
• Please clean the strap and case regularly; in the case of a leather strap, avoid contact with moisture, moisture, cosmetics, etc., and avoid exposure to the sun.
• Pay attention to the anti-magnetic of the watch, and avoid prolonged proximity to electrical appliances, mobile phones and magnets.
• Prevent the watch from being bumped or dropped.
• Do not adjust the date of the watch between 22:00 and 2:00 to avoid damage and inaccurate calendar jumps.
• If the watch needs to adjust the time, please turn the hands clockwise, not counterclockwise (except for quartz two-hand watches).

Water resistance of mechanical watches

The waterproof performance of the watch is measured by the pressure resistance value to indicate its waterproof depth, which is the reference theoretical pressure, and the unit is expressed in ATM atmospheric pressure (3ATM=30 meters deep pressure). This is not the actual diving depth used.

At the same time, many wading activities involve a lot of movement and other environmental changes. These factors that are not considered when calibrating the water resistance of the watch may result in a significant reduction in its water resistance or even failure.

The waterproof performance of the watch is not permanent, which may be affected by the aging of the waterproof ring or accidental impact on the crown, so it needs to be checked regularly by the brand-authorized repair center.

The waterproof level of the watch and the corresponding scope of application.

Water-resistant to 30 meters/100 feet or 50 meters/165 feet, it only protects against splashes and rain.

Water-resistant to 100 meters or 330 feet or 200 meters or 660 feet, it is resistant to splashes and rain and can be worn for diving and swimming.

Water-resistant to 300 meters/1000 feet, it can be worn for free diving or water sports.

Of course, there are more professional diving watches with a higher waterproof coefficient, such as Rolex's sea-dweller 116660, which can reach a waterproof coefficient of 3900 meters.

Even waterproof watches should not be used in hot baths, saunas, or environments with large temperature changes. Because the waterproof rubber ring is affected by temperature, it will expand and contract, causing voids and accelerating aging, thus affecting the waterproof function. It should be noted that, except for some models, most waterproof watches cannot operate the buttons and adjust the crown in water. At the same time, the non-screw crown should press the crown back to the normal position, and the threaded crown should be tightened to prevent water. into the watch.

Travel time error of mechanical watch

The accuracy of the mechanical watch’s time is mainly determined by the stability of the vibration frequency of the balance spring. Since the watch will be affected by many internal and external factors during use, the mechanical watch can only minimize the error range, but cannot be adjusted. to no error. At present, the normal error of mechanical watches is within plus or minus 45 seconds per day.

Mechanical watch: Insufficient power reserve, you need to check whether the power is sufficient first. If the movement of the automatic winding watch is very small, the power reserve may be insufficient. You can supplement the power by manual winding, and then observe whether there is any speed or slowness. Phenomenon.

The watch is magnetized: If the hairspring of a mechanical watch is magnetized, the time of the watch will be inaccurate.

The lack of oil in the movement or the wear and aging of the internal parts may cause the problem of running time, and it needs to be sent to the designated maintenance point for maintenance services.

Has been beaten or knocked: The watch is very precise. If it is knocked or knocked, it may cause the internal parts to loosen and damage, and may also cause time problems.

In addition to the above common situations, the influence of some ambient temperature and the influence of the wearer's usage habits may cause an increase in the travel time error. But you don't have to worry about it, please send the watch to the designated maintenance point and ask a professional to check and adjust the watch to restore the watch to the normal error range.
