We are proud to present the new Piranha ceramic-enamel dial from Ocean Crawler! This special edition watch features a hand-crafted ceramic-enamel dial. A helium release valve is located at 9 o'clock. The movement inside is a regulated Sellita SW200-1 movement. It has a beat rate of 28,800 vibrations per hour and has been enhanced for added accuracy. Due to the time intensive process to create this particular dial we will only be releasing a limited number of them. A Must-Have Underwater Accessory Every single Ocean Crawler has been immersed in water and has been thoroughly tested to withstand pressures much greater than those found under 2000 feet. This is why the Ocean Crawler is your best friend for water sports, scuba diving, spearfishing and even ocean-bed exploration.
