While water resistance is the most important function in a diver’s watch, what is equally important is the watch’s ability to relay accurately and clearly the remaining dive time. And it’s for this reason that Oris has created and now redesigned the new Regulateur Der Meistertaucher (Master Diver). The Regulateur Der Meistertaucher has non-coaxial hands, meaning the hour and minute hands are separated. The minute hand is in the centre, while the hour is shown by a hand on a sub-dial at 3 o’clock. This isolates the key piece of information for a diver, who can set dive time by aligning the minute hand to the 60-minute scale on the uni-directional rotating bezel, which in this case is fitted with a black ceramic insert with red and white markings.
The regulator dial, as this configuration is known, was introduced by clockmakers in observatories in the 18th century. These were highly accurate clocks used to set the time on standard timepieces, particularly after they’d been serviced or repaired.
In 1999, Oris became the first watch company to introduce this traditional complication into a diver’s watch. That watch was soon followed by the first Der Meistertaucher (which translates as Master Diver).
That pattern now reverses with the new Oris Regulateur Der Meistertaucher taking its design cues from the next generation Aquis, also unveiled this year. Like all the new Aquis models, it has a sleeker silhouette than the previous Aquis, and has also been given a number of practical enhancements, including an upgrade that makes the bezel easier to grip and adjust.
As before, the Regulateur Der Meistertaucher has a lightweight titanium case and bracelet. The minutes hand of this new model has a bright red outline that corresponds to the critical 15-minute scale on the bezel, and to the red rubber strap option. The result is that the eye is drawn to the minutes hand, giving the watch extraordinarily high levels of legibility.
Proving its professional watch credentials, the Regulateur Der Meistertaucher has an automatic helium escape valve, secreted on the side of the case at 9 o’clock. Automatic helium escape valves are used by professional divers who can live in chambers filled with helium-enriched air for weeks at a time during saturation dives. Helium particles are smaller than air, and during saturation they enter the watch. Then, during decompression they expand, which could cause damage to a watch without the helium escape valve.
The Regulateur Der Meistertaucher also has a small seconds indicated by a hand coated in SuperLumi-Nova® at 9 o’clock, a feature divers rely on to show the watch is still running. The watch’s automatic movement also provides a date indication at 6 o’clock. The watch has a titanium case back embossed with the Oris shield and the inscription MEISTERTAUCHER. It is presented in a water-resistant case with a red replacement strap and strap-changing tools. The original Oris regulator diving watch was a world-first and provided divers with a useful, highly legible tool they could rely on in hazardous underwater conditions. The new Oris Regulateur Der Meistertaucher continues that tradition, almost 20 years on.
