Ball Watch Company Engineer III Legend II - 40mm

The self-powered micro gas tubes provide constant and bright luminosity in darkness without requiring any external light source or battery, ensuring excellent legibility.

The luminosity from the micro gas tubes is designed to last for many years, typically up to 25 years, without fading significantly.

With 100 meters of water resistance, it is suitable for swimming and showering. However, it is not rated or designed for professional scuba diving.

The Amortiser® system is a patented rotor equipped with shock absorbers that reduce the impact transmitted to the movement, thereby protecting it from damage caused by shocks.

Chronometer-rated means the watch movement has passed stringent accuracy tests conducted by an independent official body (like COSC) and meets specific precision standards.

Yes, the watch is water-resistant to 100 meters, making it suitable for swimming and showering. However, avoid operating the crown or pushers underwater.

Generally, an automatic watch requires servicing every 3 to 5 years to ensure optimal performance and longevity of its internal components.

Ensure the watch has sufficient power. Manually wind the crown 30-40 times. If the issue persists, the watch may require servicing.

The micro gas tubes are self-powered and should always be luminous. If not visible, ensure no damage has occurred to the tubes. Contact customer support.

The primary benefit is low-light visibility. In bright conditions, the hands and markers are designed for clarity, but direct comparison with other watches may vary.

Despite the 1,000 Gauss shield, extreme magnetic fields can still affect performance. Demagnetize the watch by a professional if this is suspected.
