FAQs

What does COSC certified mean?

COSC (Contrôle Officiel Suisse des Chronomètres) certification means the watch movement has passed rigorous accuracy tests in various positions and temperatures, ensuring it meets chronometer standards.

How long do the micro gas tubes glow?

The H3 micro gas tubes provide constant luminescence for up to 25 years without needing any external light source or recharging.

Is the watch suitable for swimming?

With a water resistance of 100 meters, the watch can withstand splashes and brief submersion, making it suitable for swimming. However, it is not recommended for deep diving or activities involving high-velocity water.

What is the benefit of the mu-metal shield?

The mu-metal shield protects the watch's automatic movement from magnetic fields up to 1,000 Gauss, preventing timekeeping inaccuracies that magnetic exposure can cause.

Can I change the bracelet?

Yes, the watch is compatible with standard watch straps, allowing you to customize its look and feel.

How do I maintain the anti-magnetic properties?

Avoid exposing the watch to strong magnetic fields. If you suspect magnetic interference, consult an authorized service center for demagnetization.

What material is the case made of?

The case is constructed from 904L stainless steel, known for its superior corrosion resistance and durability compared to standard grades of stainless steel.

Troubleshooting

Watch has stopped running

Manually wind the crown by turning it clockwise about 30-40 times while in the closed position. Ensure the watch is worn regularly to keep it wound by natural movement.

Date is not changing correctly

Ensure the time is not set between 9 PM and 3 AM when the date change mechanism is engaged. Set the time to a neutral position (e.g., 6 o'clock) before adjusting the date using the quick-set function.

Losing or gaining excessive time

Minor deviations are normal for automatic watches. If timekeeping is significantly off (-4/+6 seconds per day is COSC standard), it may need a service. Avoid strong magnetic fields or shocks.

Difficulty screwing in the crown

Ensure the crown is aligned correctly and not cross-threaded. Gently push the crown inward while turning it clockwise to engage the threads. Do not force it.

Pros and Cons

Pros

  • Exceptional accuracy due to COSC-certified chronometer movement.
  • Superior low-light visibility with long-lasting micro gas tube illumination.
  • Durable 904L stainless steel construction for enhanced longevity.
  • Anti-magnetic properties protect the delicate movement.
  • Elegant yet sporty design suitable for various occasions.

Cons

  • May require professional servicing for optimal long-term performance.
  • The 40mm case size might be small for individuals preferring oversized watches.
  • While water-resistant, it is not intended for deep diving.
  • The advanced illumination technology, while powerful, is a proprietary system.

Setup, Compatibility & Care

Setup:

This watch features a self-winding automatic movement. It will begin running once you put it on and the motion of your wrist winds the mainspring. If the watch has stopped, you can manually wind it by gently turning the crown clockwise approximately 30-40 times while it is in the closed position. To set the time and date, pull the crown out to the desired position (usually two clicks for time, one for date) and make the adjustments. Ensure the crown is pushed back in securely to maintain water resistance.

Compatibility:

The watch is designed to be compatible with standard watch straps if you wish to change the bracelet. The automatic movement is self-contained and does not require compatibility with external electronic devices.

Care:

  • Clean the stainless steel case and bracelet periodically with a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners.
  • Rinse with fresh water and dry thoroughly after exposure to salt water or chlorinated water.
  • Avoid exposing the watch to strong magnetic fields (beyond 1,000 Gauss) or extreme shocks to ensure optimal performance.
  • Recommended servicing by an authorized BALL watchmaker every 3-5 years to maintain accuracy and longevity.
