4.2 Norabide bakarreko biraketa-bezel
The bezel rotates only counter-clockwise. This feature is used to measure elapsed time during a dive. Align the bezel's zero marker with the minute hand before descending. The minute hand will then indicate the elapsed time on the bezel scale. The unidirectional rotation prevents accidental increases in recorded dive time, enhancing safety.
4.3 Urarekiko erresistentzia (200 metro)
This watch is ISO 6425 certified for 200 meters (660 feet) water resistance, making it suitable for professional diving. Always ensure the crown is fully screwed down before exposing the watch to water. Do not operate the crown or pushers (if present) while the watch is wet or submerged. This watch is not designed for saturation diving requiring helium gas.

6.3 Fogging Under Crystal
Temporary fogging on the inside of the crystal can occur due to sudden temperature changes. If the fogging persists or appears as droplets, it may indicate a loss of water resistance. Immediately have the watch inspected by an authorized service center.
