Zenith Defy Extreme Glacier - 45mm - Blue

The 'Glacier' moniker and the watch's aesthetic, particularly the frosted sapphire dial and pale blue chalcedony bezel, are inspired by the dramatic beauty and resilience of icy, frozen landscapes.

Yes, the bezel is made from a natural chalcedony gemstone. Each watch features a unique variation in structure and color due to the nature of the gemstone.

The El Primero 21 movement is a high-frequency automatic chronograph movement known for its precision. The inclusion of two regulating organs and escapements further enhances its accuracy and performance capabilities.

To maintain the full power reserve, wind the watch manually for about 40-50 turns of the crown when not worn for an extended period (more than two days). Regular wear also keeps the mainspring wound.

With a water resistance of 20 bar (200 meters), the watch is suitable for swimming, snorkeling, and other water sports. However, it is not recommended for deep-sea diving without professional equipment.

Yes, the robust titanium case and 200m water resistance make it suitable for daily wear. However, given its limited edition status and unique materials, some owners prefer to reserve it for special occasions.

Manually wind the crown 40-50 times in the closed position. If the issue persists, ensure the watch has not been subjected to strong magnetic fields or impacts.

Ensure the chronograph pusher is fully engaged when starting and stopping. If the hands do not return to zero, a service by an authorized watchmaker may be required.

Mechanical watches can be affected by magnetism or extreme temperatures. Try demagnetizing the watch if possible, or consult an authorized service center for recalibration.

Do not attempt to tighten the bezel yourself. Contact an authorized Zenith dealer or service center for inspection and repair.
