RATIO FreeDiver Dive Watch Sapphire Crystal GMT Rotating

Product Overview

The RATIO FreeDiver Dive Watch is a precision-built automatic timepiece engineered for serious divers and watch enthusiasts who demand reliability, functionality, and rugged durability. Designed for men who explore both underwater and international time zones, this watch combines professional-grade diving capabilities with practical GMT tracking. At its core lies the trusted NH34 automatic movement, delivering consistent performance and a 40-hour power reserve for uninterrupted wear. The unidirectional rotating bezel, clearly marked with 24-hour GMT graduations, allows wearers to monitor a second time zone—ideal for travelers or those coordinating across regions. Built with a 316L stainless steel case and rated for water resistance up to 200 meters, this watch is built to withstand the pressures of deep-sea diving and everyday adventures alike. Whether you’re descending into the ocean depths or navigating global time zones, the FreeDiver is designed to keep accurate time in demanding environments.

Key Features

• Automatic NH34 Movement: Powered by a self-winding mechanical movement, the NH34 ensures reliable timekeeping without the need for batteries. It offers a 40-hour power reserve, meaning the watch continues running for nearly two days after being fully wound—perfect for weekend excursions or extended wear. This movement is known for its robustness and accuracy, making it a favorite among mechanical watch enthusiasts.
• GMT 24-Hour Rotating Bezel: The unidirectional bezel is precisely engraved with 24-hour markings, enabling users to track a second time zone simultaneously. This feature is especially useful for pilots, international travelers, or professionals working across global time zones. The bezel rotates smoothly and locks securely, providing tactile feedback with each click to ensure accurate time tracking.
• 200M Water Resistance: Engineered for serious diving, this watch is rated for depths up to 200 meters (660 feet), meeting ISO standards for recreational scuba diving. It’s suitable for snorkeling, swimming, and underwater exploration in most aquatic environments. The screw-down crown enhances water resistance by sealing the case tightly against moisture.
• 316L Stainless Steel Case: Known for its exceptional corrosion resistance and strength, the 316L stainless steel construction ensures long-term durability in saltwater and harsh conditions. The material maintains its finish over time, resisting scratches and tarnishing. This makes the watch suitable for daily wear in both urban and marine settings.
• Sapphire Crystal: The watch face is protected by scratch-resistant sapphire crystal, one of the hardest transparent materials available. This ensures superior clarity and protection against daily wear, keeping the dial legible in all lighting conditions. Sapphire crystal is significantly more durable than mineral or acrylic glass, offering peace of mind during active use.
