Ollech & Wajs • OW Navichron Chronograph

Named after a long line of OW specialty chronographs, the new Navichron is well suited to the conditions facing professionals and sportsmen around the world. A Valjoux 7753 based two-counter chronograph with a 12-hour sliding bezel, enabling travelers to determine time across different zones. But it is also a professional diving watch, its specially reinforced case, extra-thick sapphire glass, and unique 4 gasket pushers capable of withstanding over 50 atm of pressure, as well as markings for diving times on its bezel. Its baton style markers and hands feature Super-LumiNova®, to ensure maximum visibility in all conditions.

The Navichron’s movement pursues a long tradition of Valjoux chronographs, with historical references such as the V72, V92, V7730, V7733, and V7750. OW has devised its own PRECISION quality rating, which we start with a Valjoux 7753 with a brutalist matte finish, which we then reassemble with our own OW machined rotor, after which we engrave the mainplate with our brand, before removing the hours counter. We then reassemble it, regulate it, and then test its precision in 5 positions, as well as its duration.
