What Defines a Professional Dive Watch?
A professional dive watch is held to stricter standards than casual sports or lifestyle watches. Its primary role is safety: allowing divers to track bottom time, decompression stops, and elapsed intervals without failure.
Core Requirements
ISO 6425 Certification (preferred): International standard for dive watches.
Water Resistance: At least 200 meters, ideally 300m+.
Unidirectional Rotating Bezel: Prevents accidental extension of dive time.
Legibility: Large markers, luminous coating, high contrast.
Shock and Magnetic Resistance: Protects against harsh environments.
Helium Escape Valve: For saturation diving.
