Benrus revives one of its best-selling dive watches with the new Benrus Ultra-Deep, a recreation of one of the watchmaker’s historic models from the 1960s.
Originally created in response to the rise of scuba diving for sport, the Benrus Ultra-Deep retains the 36.5mm case size of the original model’s ‘compressor’ case. Such cases, built for the U.S.-based Benrus by Swiss-based Ervin Piquerez, would become more water resistant as the diver went deeper because the caseback would pressurize. Modern screw-down cases fulfill the same role in new watches.
The revived Benrus Ultra-Deep also retains the dual-crown design found on the original model.
One crown rotates an inner timing bezel instead of an external bezel, which makes it less likely the bezel will be shifted by mistake, leading to timing errors under water.
Also note the same cathedral-style hour and minute hands and magnified date window as the original.
The new models of course benefit from numerous technical updates, including a screw-down winding crown, C3 SuperLumiNova hands and dial markers. Inside, Benrus fits a reliable Soprod P024 automatic movement. The watch arrives on a high-end Jubilee-style stainless steel bracelet and also includes a blue nylon NATO dive strap.
