Features
Movement
It is powered by the Japanese-made automatic Caliber NH34 movement, with a power reserve of up to 40 hours. This movement is specifically designed for watches with GMT functions.
GMT Function
A key feature is the dedicated GMT hand, which allows you to track a second time zone simultaneously with the local time. The bezel is also marked with a 24-hour scale to assist with this.
Water Resistance
The watch is water-resistant to 200 meters (20 ATM), making it suitable for swimming, snorkeling, and general water sports, though it's not a professional diver's watch like some of the other FreeDiver models with a higher rating.
Case and Crystal
The case is made of 316L stainless steel with a diameter of approximately 40mm. The dial is protected by a scratch-resistant sapphire crystal with an anti-reflective coating. It also features a screw-down crown and an engraved case back with a free diver image.
Dial
It has a black dial with luminous hands and markers for low-light visibility and a date display at the 3 o'clock position.
