Big Crown Calibre 473

No mistake, this is a special watch. Why? Because it breathes new life into our signature design, the iconic Big Crown Pointer Date, an Oris collection mainstay since 1938. For the first time in decades, it has a hand-wound in-house Oris calibre inside it, Calibre 473. And that’s a magical thing. The story of Calibre 473 is that it’s built on the same base as the Oris Calibre 403 automatic. So it has hour, minute, small seconds and pointer date hands, and a five-day power reserve, now shown by a 120-hour power reserve indicator on the back of the movement. Calibre 473 took four years to develop and closes a circle for Oris. Without a rotor, the power reserve indicator is visible through the watch’s sapphire case back. Oris watchmakers designed it to be simple to produce and assemble, and extremely durable, in line with our movement creation philosophy. We’ve filed a patent for it. As with Calibre 400 Series movements, Calibre 473 also has elevated levels of antimagnetism, and each watch powered by it will come with a 10-year warranty and 10-year recommended service intervals. Pure joy.
