For daily wear, avoid strong impacts, frequent knocks, and rough handling of the crown and pushers. Most importantly, avoid hot-water exposure (showers, saunas, prolonged hot water contact), as heat can accelerate seal aging and increase water-ingress risk. If the watch includes a date function, avoid adjusting the date during the typical “danger zone” hours (commonly late evening to early morning) unless you are certain the movement is designed for safe quickset use at that time.

Watches are designed to handle everyday activities such as hand washing or brief exposure to moisture. However, swimming, bathing, or contact with hot water is not recommended, as heat can degrade seals and significantly increase the risk of water ingress.

Water resistance should be understood by movement type and construction level:

• Asian-movement models are intended for basic daily water resistance only (light splashes and routine wear).
• Swiss-movement and true 1:1 clone models are typically engineered with higher water-resistance standards, commonly rated between 30 to 300 meters, depending on the specific model and case structure.

Actual water resistance may vary due to model design and assembly tolerances. For precise ratings and usage limits, please refer to the individual product specifications.

These watches are generally built for normal daily environments, not extreme conditions. Strong magnetic fields (certain speakers, magnetic clasps, industrial magnets) and heavy shocks can affect timekeeping or movement components. If you work around magnets or impact-heavy activity, it is best to treat the watch as a precision device rather than a tool watch.

Basic maintenance is recommended, but excessive disassembly is unnecessary. Under normal daily wear and reasonable care, a high-quality movement can remain stable for many years. A practical approach is periodic checks based on timekeeping performance, winding feel, and water-resistance needs, rather than servicing on an overly frequent schedule.

Common issues are often related to usage and environment: water ingress, hot-water exposure, crown misuse, improper date-setting, or impact damage. Repairability depends on the movement architecture and parts availability; mainstream movement structures are generally serviceable. If a complication is important to you, confirm that it is truly functional at the movement level.
