Triangular Groove Pattern, Honeycomb Embossed Silver Plate Promotional Watch Calendar Window Steel Strap Luxury Men's Automatic Mechanical Watch

Automatic mechanical watches have a reasonable margin of error, with variations of 15 seconds per day falling within normal ranges. After receiving the watch, it needs to be fully wound and worn for 3 to 5 days. Once the movement has been properly adjusted, the watch will run more smoothly.

It is water-resistant and can withstand rain and splashes from washing hands. However, it is not suitable for hot water baths, saunas, or diving. High temperatures can damage the waterproof sealant, leading to water ingress.

A mechanical watch will stop if it is left idle. Rotate the crown in a clockwise direction for about 30 turns to wind it up, then gently shake it back and forth a few dozen times, and it will start functioning normally.

The luminous coating requires absorption of natural light or artificial light in order to glow. It does not shine in dark environments. Place it in a dimly lit area, and after exposing it to strong light for a few minutes, it will regain its luminous effect.

The steel strap does not typically fade when worn normally. The gold-plated version, which is exposed to sweat and chemicals over time, may undergo slight oxidation. Regular wiping can help mitigate this oxidation.
