Core Diver - Whitewater Sentinel

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 do ocean-bed exploration.

This special edition watch features a fully lumed BGW9 dial and an all Sapphire unidirectional rotating bezel which bears hour-markers filled with seven layers of Swiss C3 Lume. Powerful C3 Lume on the key elements guarantees perfect readability when deep diving.

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 Whitewater Sentinel Core Divers and all are stamped with a unique serial number out of a total of 100.

A Must-Have Underwater Accessory

Every single Core Diver 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 Core Diver is your best friend for water sports, scuba diving, spearfishing, and even ocean-bed exploration.
