Deep Descent

Returning to the deep with the new ProDiver watch.

Oris presents the new Oris Dive Control Limited Edition as the new addition to their ProDiver watch collection. This watch was developed in partnership with Roman Frischknecht, a Swiss commercial diver who services the subsea industry.

As a deep sea diver, Roman puts safety of his co-divers and his self above everything else. He often spends days at a time on deep dive assignments. You need to be able to trust your partners, just as much as you need to trust each and every piece of equipment you use.

As a seasoned diver, Roman was the perfect pick to assist in designing the perfect dive watch. Roman has already collaborated with Oris in designing one of the crucial functions of a dive watch: the unidirectional rotating bezel. The bezel is used to time a dive, informing the diver of how much air he approximately has remaining. If the rotating bezel were to scrape on some coral, it may turn and give the diver the wrong information on how much air he has left. To solve this problem, Oris worked closely with Roman on a system that will give the diver the correct information at all times. The system is called the Rotation Safety System, patented by Oris and found on every ProDiver watch.

To avoid accidental turning of the bezel, Oris and Roman worked on a system that will lock the bezel into place. On its normal stage, the outer ring of the bezel may be rotated, but the minutes counter on top will stay in place. To set the dive time, hold the bezel’s edge and lift it. This will release the RSS’s lock, engaging the minutes scale on top. Next, turn the top ring counter-clockwise and align the number that corresponds to your dive time to the minutes hand. Once in place, push the ring down until it clicks. The timer scale is now secure and you are ready to begin your dive.

The Rotation Safety System is found on the new Oris Dive Control Limited Edition watch. Also featured on this timepiece is an oversized 51 mm case that is cast in lightweight black DLC-coated Grade 2 titanium, water resistant to 100 bar (1,000 meters). Oris engineers made sure that the watch would work perfectly on that depth, so they subjected the watch to a pressure test to an astonishing 125 bar.

Working as deep as they do, divers need to be able to see all of their equipment clearly. To improve on legibility, the watch’s dial is oversized, too. The hands, hour markers, and zero marker on the bezel are all filled with Super-LumiNova®. Oris designers used high-contrast yellow details to indicate critical information. The colour yellow was used because it is one of the most visible colors seen in those depths.

Like all deep dive watches, the Oris Dive Control Limited Edition comes with an automatic helium escape valve. Working deep below sea level, helium atoms (which are smaller than oxygen atoms) can enter a watch. Without the helium escape valve, these atoms can damage the watch once it enters regular air pressure on the sea level.

Roman Frischknecht said, “In the companies I work for, safety standards are high and the equipment very reliable. Commercial diving has become one of the most safety-conscious professions in the world.” In Roman’s line of work, you have to be 100% sure of everything that you do, whether you are operating the equipment or recording the readings of the gauges or displays. Every action must be done with unquestionable certainty. When collaborating with Oris in designing watches, Roman applies the same conviction and importance of safety and reliability to ensure that the watch is fit to be used under the most extreme conditions.

The Oris Dive Control Limited Edition has a multi-piece Grade 2 titanium case that has a black DLC coating. It sports a ceramic minutes scale on the top ring. It measures 51 mm in diameter. The case back is also made of titanium, black DLC plated, is screwed down, and bears special markings. It employs a stainless steel screw-in security crown and screw-in pushers, and has an automatic helium escape valve. And, as also mentioned earlier, has a water resistance of 1,000 meters.

Inside the case beats the Oris Cal. 774 an automatic movement that has centre hands of hours, minutes, and chronograph 1/4 seconds, 3 subsidiary dials for continuous seconds, 30 minutes, and 12 hours counter, a date window, date corrector, fine timing, and stop-second. It has a power reserve of 48 hours and beats at a frequency of 28,800 A/h. It comes with a black rubber strap with folding clasp and a quick-adjust extension system. Limited to only 500 pieces, the Oris Dive Control Limited Edition comes in a waterproof presentation box with additional rubber strap and changing tools
