Key Features
- NH35 Automatic Movement – A self-winding mechanical movement that harnesses kinetic energy from wrist movement to power the watch, eliminating the need for battery replacements and offering long-term reliability.
- 200M Water Resistance – Rated for depths up to 200 meters (20 ATM), this watch is suitable for swimming, snorkeling, and recreational scuba diving, making it a dependable companion for water-based activities.
- Sapphire Crystal – One of the hardest transparent materials available, sapphire crystal resists scratches and impacts, keeping the dial pristine even in demanding environments.
- Full Bezel Lume – The unidirectional rotating bezel is fully coated with luminous material that absorbs light and glows in darkness, allowing for accurate time and elapsed-time tracking during low-light dives or nighttime use.
- 316L Stainless Steel Strap – Known for its excellent corrosion resistance, this premium-grade steel band withstands exposure to sweat, moisture, and saltwater, while the secure buckle ensures a comfortable and reliable fit.
- 40mm Black Dial with Casual Styling – The balanced case size and minimalist black dial make the watch versatile enough for both active use and everyday wear, complementing tactical gear or casual attire with equal ease.
- Screw-Down Crown – This essential feature enhances the watch’s water resistance by creating a tight seal when fully tightened, preventing water from entering the case during submersion.

The Cronos dive watch is ideal for men who value both function and form. Its 200-meter water resistance and screw-down crown make it a trustworthy choice for diving, swimming, and other water sports, while the full luminous bezel and dial ensure critical visibility in dark or murky conditions.

The 40mm case offers a comfortable, proportional fit on most wrists, avoiding the oversized look of some tactical watches while still making a strong visual statement. The 316L stainless steel construction resists rust and wear, making it suitable for daily exposure to sweat, rain, and saltwater. Beyond its diving credentials, the watch’s clean black dial and casual styling allow it to blend seamlessly into everyday life—whether you’re at work, on a hike, or out for the weekend. The automatic movement appeals to those who appreciate mechanical watchmaking and prefer the tradition of self-powered timekeeping over quartz alternatives. With no battery to replace, the watch becomes a long-term companion that grows more personal with each wear.
