Product Overview
The Steeldive 1000M Waterproof NH35 Dive Watch is a rugged, precision-engineered timepiece built for serious divers and watch enthusiasts who demand reliability under pressure. Designed for men who value both form and function, this 45.4mm automatic mechanical watch combines professional-grade diving capabilities with everyday wearability. At its core lies the reliable NH35 automatic movement, known for its durability and consistent performance. Whether you’re exploring underwater environments or navigating daily life, this watch delivers the confidence of 1000 meters of water resistance and a robust construction that stands up to real-world use.
Key Features
- NH35 Automatic Mechanical Movement: Powered by the trusted NH35 caliber, this movement features two-way automatic winding, a frequency of 21,600 vibrations per hour (3Hz), and a 41-hour power reserve. With 24 jewels and a stop-second device for precise time setting, it ensures accurate and reliable timekeeping without the need for batteries.
- 1000M Water Resistance: Engineered for deep-sea diving, this watch is rated for 1000 meters of water resistance. It’s suitable for professional diving, swimming, snorkeling, and all daily water-related activities. The screw-in crown and solid screw-down case back contribute to its exceptional sealing performance.
- Sapphire Crystal with Anti-Reflective Coating: The watch face is protected by double-curved artificial synthetic sapphire glass with an anti-dazzling blue coating. This enhances clarity in bright conditions and resists scratches from everyday wear, ensuring long-term legibility.
- Ceramic Bezel with 120 Clicks: The unidirectional rotating bezel is crafted from durable ceramic and features 120 precise clicks for accurate timing during dives. Its single-direction rotation prevents accidental overcounting of elapsed time, a critical safety feature for underwater use.
- 316L Stainless Steel Construction: The case and bracelet are made from high-grade 316L stainless steel, known for its corrosion resistance and strength. The finishing combines sanding and polishing for a balanced, professional look that resists wear in harsh environments.
- Helium Escape Valve: Equipped with an exhaust valve, this watch is designed for saturation diving. The valve allows helium molecules to escape during decompression in hyperbaric chambers, preventing damage to the watch during prolonged deep dives.
- Large 45.4mm Case Design: With a substantial case diameter of 45.40mm (excluding the crown) and a thickness of 17.10mm, this watch makes a bold statement on the wrist. The 22mm lug width ensures compatibility with a wide range of replacement straps.
