Self Winding & Manul Winding: This mens watch uses Miyota 8215 automatic movement for providing and keeping a highly precise time. It supports both automatic and manual winding. The watch has a long power reserve of more than 41 hours. Please note that if the watch is not worn for over 42 hours, you need to manually wind it at a fixed time to ensure that it continues to run properly.

Reliable Quality: Ergonomically designed, mechanical automatic watch fits perfectly on your wrist. The watch case is made of 304L stainless steel, paired with high-hardness sapphire glass, which offers excellent scratch resistance. It comes in three colors to choose from: blue, green, and black dials, each matched with a corresponding waterproof silicone strap. The overall design is harmonious, stylish, and durable.

Bidirectional Rotating Inner Bezel: Enhancing functionality, diving watch includes an inner bezel situated beneath the crystal that can be easily rotated using the crown at 2 o'clock. Clear scales and numbers on the inner bezel facilitate effortless timekeeping, while the dual fluorescence (orange for the first 15 minutes and blue for the subsequent 45 minutes) on the diving watch rotating bezel serves as a vital tool for underwater safety and time management.
