Ball Engineer Master II Diver GMT Black
April 28, 2008
Guillaume Nery is a three-time free dive world record holder and brand ambassador to Ball Watch Company. He makes dives without assistance or equipment on a regular basis to depths of 100 meters (330 feet). This is not only hard to do, it is hard to see while doing it. The ambient light is about 1% of surface light at these depths. This is where the 53 micro gas tubes (tritium) come in very handy and why he uses the EMII Diver GMT watch. The watch has a rotating inner bezel the utilizes 41 of the gas tubes with the remaining 12 being placed on the hands and dial. This illumination setup is very beneficial and allows divers to see their watch at any depth.
The stainless steel case is the same design as the older model, except they have given it some DLC or Diamond Like Carbon. This gives it a fantastic gunmetal grey look and adds to the hardness, scratch resistance, reduces friction and even provides electrical insulation.
The crowns operate underwater to adjust the time or elapsed minutes ring with no problem, which is of course crucial to any professional diver. When the crowns are unscrewed red-o-rings are visible which is part of the water tight gasket system that ensures water resistant down to 300 meters, or 1000 feet.
The movement is automatic calibre ETA 2893-2 and has hours, minutes, sweep seconds, second timezone and date. The case is 42 mm in diameter by 14.3 mm thick. The crystal is an anti-reflective sapphire crystal. The model number is DG1020A- PAJ-BK and costs about $2600 USD, based on todays commercial exchange rate.
Two versions are pictured, one with silver accents on the dial and one with gold. They should be available at retailers this summer.
