Selling my OC Core Diver. These sold for $999 brand new several years ago. The Core Diver has been designed to be the ultimate diving watch. Every single Ocean Crawler has been immersed in water and has been thoroughly tested to withstand pressures up to 2000 feet. The Core Diver is a must-have underwater accessory for water sports enthusiasts who scuba dive, spearfish, and even ocean-bed exploration. This special edition watch features an all Sapphire unidirectional rotating bezel that bears hour-markers filled with seven layers of Swiss C3 Lume. Powerful C3 Lume on the key elements guarantees perfect readability when deep diving. Each timepiece includes both, a shark mesh bracelet, and a rubber strap, both included in this sale. The clasp for the mesh bracelet has a quick adjust mechanism. The movement inside the Core Diver 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. There are only 100 units per color made of the Core Divers and all are stamped with a unique serial number out of a total of 100. This is 051/100.
