RATIO - FreeDiver Helium Safe 1000M Stainless Steel Automatic 1066KE20-33VA-GRN Men's Watch - Green and black

The Ratio Free Diver Helium Safe automatic watch offers an enjoyable and safe feel when you are deep down under water. It is surprisingly accurate and amazingly resilient to shocks and bumps, similar to other dive watches costing more than a few times. Its solid construction ensures a hassle-free dive while the helium valve is an added safety option that will keep your watch safe in case you decide to go for deep-sea diving.

• Movement: It's an automatic watch powered by the reliable Seiko NH35 caliber. This movement is known for its durability, and it features both hacking (the second hand stops when the crown is pulled out for precise time setting) and hand-winding capabilities.
• Water Resistance: This is one of its most impressive features. The watch has a water resistance rating of 1000 meters (100 ATM), making it a professional-grade dive watch suitable for extreme deep-sea diving and saturation diving.
• Helium Safe Valve: It is equipped with a helium escape valve (HEV). This is a crucial feature for professional divers who use a helium-oxygen gas mix. The HEV allows helium atoms that have seeped into the watch case during a dive to escape during decompression, preventing the watch crystal from being damaged or "popping off" due to a pressure imbalance.
• Dial: The dial is a vibrant green color, which provides a striking contrast and excellent legibility against the stainless steel case. The hands and markers are treated with lume (luminescent paint) to ensure visibility in low-light conditions, both underwater and on land.
• Bezel: It has a unidirectional rotating bezel, a standard feature on dive watches used to track elapsed time. The bezel has serrations to facilitate a firm grip, even with wet fingers or gloves.
