Men's Black Automatic Dive Waterproof Mechanical Movement Silicone Band Watches

Self-Winding Automatic Watch: Powered by the Miyota 8205 automatic movement, this men's watch delivers precise timekeeping without a battery — harnessing energy from the natural motion of your wrist. For optimal performance, wear it at least 10 hours per day. If unworn, manually wind the crown at a fixed time. When first using the watch, wind the crown about 20 turns to initiate operation.  High Quality: This men's automatic wristwatch features a highly scratch-resistant sapphire crystal and an exhibition case back, combining exceptional durability with a captivating view of the intricate mechanical movement inside. Paired with a silicone strap, it ensures all-day comfort.  20ATM Waterproof: The BERNY diver's watch features screw-down crowns for enhanced water resistance, rated to 200m (20ATM)—ideal for swimming and recreational diving. Its bidirectional rotating bezel provides precise underwater timing, a critical safety feature for divers.  Super Luminous: Designed for both style and functionality, the watch features bold straight-bar indices and Arabic numerals, along with a practical day and date display positioned at 4 o'clock. The luminescent coating on the hands and markers guarantees clear readability in dark environments.
