The SEA version comes in a 42 mm CARBONOX™ case, water resistant to 200 meters, perfect for no decompression air diving. The uni-directional 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 has an orange rubber ring, for better grip, and the color matches the markings on the bezel and the minute and second hands (the most visible color for underwater work). The SEA series comes with a waved black rubber strap.
