Key Features

• Automatic NH35 Japanese Movement: Powered by the renowned Seiko NH35 caliber, this self-winding movement offers reliable accuracy and a smooth sweep of the second hand. It includes a power reserve that keeps the watch running even when not worn, reducing the need for frequent resetting.

• Helium Escape Valve: A critical feature for technical divers, this valve allows trapped helium to safely escape during decompression in saturation diving, preventing damage to the watch casing.
• Luminous Hands and Markers: High-brightness luminescent material coats the hands and hour markers, ensuring excellent visibility in dark underwater conditions or low-light environments.
• Unidirectional Rotating Bezel: The engraved bezel allows divers to track elapsed time underwater accurately, with a secure grip for easy adjustment even when wearing gloves.
• Screw-Down Crown: Enhances water resistance by sealing the crown tightly against the case, protecting the internal movement from water and dust intrusion.
