Luminox Bear Grylls Survival SEA 3720 Series 3723 Black/Blue

The Sea version comes in a 42mm Carbonox case, water resistant to 200 meters. The unidirectional turning bezel has a special diving zone count up marking, set off by a different color (blue or orange) for easy reading.

The screw-down crown ring, for better grip, and the color matches the marking on the bezel and the minute and second hands (one of the most visible colors for underwater work). The SEA series comes with a waved black rubber strap.

• Carbonox
  • Luminox uses an innovative carbon compound material – CARBONOX – for its ultra-lightweight watches. CARBONOX is six times lighter than steel, three times lighter than titanium, very low thermal extension, low heat expansion and is weatherproof – creating a very rigid and hard finished watch case that takes ruggedness and durability to a whole new level.
