TACTICAL FROG 43mm Automatic Watch Sapphire Crystal Luminous
Product Overview
The Tactical Frog Sub 300T V3 is a rugged, precision-built automatic diving watch engineered for men who require dependable performance in challenging conditions. At its core lies the Japanese NH35A automatic movement, a self-winding mechanism celebrated for its consistency and low maintenance. Housed in a 43mm surgical-grade stainless steel case with a brushed finish, this timepiece balances durability with a refined aesthetic. The sapphire crystal, treated with an anti-reflective (AR) coating, resists scratches and minimizes glare, ensuring clear readability in bright sunlight or underwater. With a water resistance rating of 20 ATM (200 meters), it’s built to perform during recreational scuba diving, snorkeling, swimming, and other water-based activities. The screw-down crown further enhances protection against water ingress, making this watch a reliable companion for both aquatic adventures and daily wear.
Key Features
- NH35A Automatic Movement: This Japanese-made movement powers the watch without batteries, relying on natural motion from the wearer’s wrist. It features a hacking second hand, which stops when the crown is pulled out, allowing for precise time synchronization—ideal for divers and professionals who need accurate timing.
- 20ATM Water Resistance (200m): Certified for depths up to 200 meters, the watch meets the demands of recreational diving and water sports. The screw-down crown creates a tight seal, maintaining integrity under pressure.
- Sapphire Crystal with AR Coating: The watch face is shielded by scratch-resistant sapphire crystal, one of the hardest materials used in watchmaking. The anti-reflective coating reduces glare, improving visibility in direct sunlight or underwater.
- Unidirectional Rotating Bezel: The outer bezel rotates in 120 distinct clicks, moving only counterclockwise to prevent accidental overestimation of dive time—a critical safety feature. The inner bezel is fixed and does not rotate.
- C3 Green Luminous Display: Both the hands and hour markers are coated with high-intensity C3 luminescent material, providing a bright, long-lasting glow in dark or low-visibility environments such as deep water or nighttime settings.
- Surgical Grade Stainless Steel Case: Crafted from corrosion-resistant stainless steel with a brushed finish, the case maintains its appearance over time and withstands exposure to saltwater and moisture.
- 43mm Case with 20mm Band Compatibility: The 43mm diameter offers a substantial yet wearable presence on most wrist sizes. The 20mm lug width allows for easy strap customization with a wide range of aftermarket or OEM bands.
