Automatic Movement: Equipped with a Miyota 8215 automatic movement that guarantees accurate timekeeping, it supports both automatic and manual winding. With an impressive power reserve of over 41 hours, it delivers reliable performance every day. Note: Manual winding is recommended if you will not be wearing the watch for more than 42 hours. Reliable Quality: Designed for ergonomic comfort, this watch features a PVD-coated 316L stainless steel case that fits snugly on the wrist and offers superior durability. A scratch-resistant sapphire crystal protects the beige dial, and a comfortable silicone strap enhances its stylish and durable appearance. Dual Crown: To enhance functionality, it features an easy-to-use dual crown. The inner bezel beneath the crystal can be adjusted with the crown at the 2 o'clock position. The other crown at the 4 o'clock position, in addition to the conventional winding and timing functions, features a 60-minute bidirectional rotating bezel and two hands coated with luminous paint for clear visibility. BERNY diver's watches are designed for underwater exploration and feature a screw-down crown for enhanced water resistance. With 20 ATM (200m) water resistance, they are ideal for swimming and diving. They also feature luminous paint for visibility in dark conditions. The dial is made of sapphire glass. Sapphire glass is highly hard, scratch-resistant, and can clearly display the time even in all adverse conditions.
