RATIO FreeDiver Dive Watch Sapphire Crystal GMT Rotating
Product Overview
The RATIO FreeDiver Dive Watch is built for men who value precision, durability, and versatility in a single timepiece. At its core lies the automatic NH34 movement, a reliable self-winding mechanism that delivers a consistent 40-hour power reserve. This means the watch keeps accurate time as long as it’s worn regularly or stored in a watch winder—no batteries required. Designed with both underwater exploration and global travel in mind, the FreeDiver features a 24-hour GMT-marked unidirectional rotating bezel, allowing you to track a second time zone at a glance. The 316L stainless steel case offers excellent resistance to corrosion, especially in saltwater environments, while the sapphire crystal face provides exceptional scratch resistance for long-term clarity. With a water resistance rating of 200 meters, this watch is suitable for recreational diving, snorkeling, swimming, and everyday wear in demanding conditions.
Key Features
- Automatic NH34 Movement: This mechanical movement operates without a battery, harnessing the motion of your wrist to stay powered. It maintains a 40-hour power reserve, ensuring reliable timekeeping whether you’re active or at rest. Ideal for watch enthusiasts who appreciate traditional craftsmanship and low-maintenance performance.
- 24-Hour GMT Rotating Bezel: The unidirectional bezel is clearly engraved with 24-hour markings, enabling you to monitor a second time zone—perfect for frequent travelers, pilots, or remote professionals coordinating across continents. The bezel turns smoothly and locks securely to prevent accidental adjustment.
- Sapphire Crystal Face: Renowned for its hardness, sapphire crystal is second only to diamond in scratch resistance. This ensures the dial remains clear and unmarred, even after exposure to sand, keys, or other abrasive surfaces commonly encountered during travel or outdoor activities.
