Uniquely numbered case back, the highly-regarded Submariner with black Cerachrom ceramic bezel is now available in Diamond-Like Carbon by Pro-Hunter. Super-tough, this crystalline coating renders the watch impervious to daily damage. The single line of red text on the dial is in deference to the collectible and historic "Red-Writing Submariner" of the 1970s. Limited to an edition of 100 and fitted to the diver's Oyster bracelet with Glidelock clasp, the watch comes with the certificate and box, and is guaranteed for two years by Pro-Hunter.
