Product Overview

The BERNY Automatic Mechanical Dive Watch is a precision-built timepiece designed for men who value reliability, durability, and performance in demanding environments. Built for diving, water sports, and everyday wear, this self-winding mechanical watch operates without a battery, harnessing the natural motion of your wrist to keep accurate time. With its rugged silicone strap, sapphire glass crystal, and 20ATM waterproof rating, it’s engineered to withstand extreme underwater conditions while maintaining a sleek, sporty profile. Ideal for divers, outdoor enthusiasts, and watch collectors, the BERNY dive watch combines functional excellence with long-term mechanical craftsmanship.

Key Features

• Automatic Mechanical Movement – No battery required. The watch winds itself through the natural movement of your wrist, ensuring continuous operation as long as it’s worn regularly. This traditional mechanical system offers a classic watchmaking experience with modern reliability.
• 20ATM Waterproof Rating (200M) – Rated for depths up to 200 meters, this watch is suitable for professional marine activity, serious surface water sports, and recreational diving. The robust construction ensures integrity under pressure, making it a trusted companion in aquatic environments.
• Sapphire Glass Crystal – The watch face is protected by scratch-resistant sapphire glass, one of the hardest transparent materials available. This ensures exceptional clarity and long-term resistance to scratches from daily wear, sand, or accidental impacts.
• Super Luminous Display – Equipped with high-brightness luminous material on the hands and hour markers, the watch delivers excellent visibility in low-light or dark underwater conditions. The glow lasts for hours after brief exposure to light.
• Screw-in Crown – The threaded crown enhances water resistance by creating a secure seal against moisture and dust. Properly tightened, it maintains the watch’s integrity at depth and during active use.
• Fluoroelastomer Silicone Strap – The strap is made from fluoroelastomer, a high-performance material known for its resistance to heat, chemicals, and degradation over time. It offers a comfortable, flexible fit that stays secure during movement and resists wear from saltwater and UV exposure.

Important Notes

The BERNY Automatic Mechanical Dive Watch comes with a manufacturer’s warranty; for specific warranty details, please refer to the product documentation or contact the manufacturer directly. To maintain optimal performance, ensure the screw-in crown is properly tightened after setting the time, especially before water exposure. Regular wear helps keep the automatic movement fully wound; if the watch will not be worn for an extended period, consider using a watch winder to preserve functionality. Avoid exposing the watch to strong magnetic fields or extreme temperature changes, which may affect mechanical accuracy. The package includes the watch only; additional accessories or tools are not included unless specified by the seller.
