Key Selling Points

• SUS316L Surgical-Grade Stainless Steel Throughout the Entire Structure: Case, bezel, case back, and bracelet forged from SUS316L steel, a molybdenum-containing alloy that prevents corrosion from seawater and significantly reduces the risk of skin irritation or allergic reactions.
• F6N47 Caliber with Power Reserve Indicator: Features Orient’s prestigious complication, which allows you to see at a glance how much mechanical energy remains in the mainspring (from 0 to 50 hours), preventing the watch from stopping unexpectedly during an activity.
• Royal Scuba Diver’s 200 m Certification: This is not merely a watch with a diver aesthetic, but a certified tool for recreational and technical diving, backed by a fully screw-down crown and case back and high-pressure gaskets.
