The Core Diver GMT 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 GMT is a must-have under-water 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 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 GMT is a regulated Sellita Caliber SW330-2 movement. It has a beat rate of 28,800 vibrations per hour and has been enhanced for added accuracy.
The Blue steel case is achieved through Plasma Assisted Deposition – a process commonly used in medical components and implants for its hardness and scratch resistance
Every single Core Diver GMT 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 GMT is your best friend for water sports, scuba diving, spearfishing, and even ocean-bed exploration.
There are only 100 units per color made of the Blue Steel DLC Core Diver GMTs and all are stamped with a unique serial number out of a total of 100.
