On this BC4 Blue Eagle model, the case features the exclusive "cushion" shape of the BC4 collection, but larger and bolder (45 mm in diameter). The bezel and caseback have a beautiful black DLC coating, and the silver reflections of the steel case middle give the watch a very original "sandwich" structure! The black is also found on the dial, with the Blue Eagle Association logo at 6 o'clock.

The central 24-hour time display, which was a first for Oris when this model was released, guarantees an unparalleled glance at the time. It is powered by the Oris Calibre 653 movement. The day and night zones are highlighted in black and white for optimal visibility. The inner bezel is activated by the large vertical crown at 2 o'clock to display a second time zone. The crown is equipped with an exclusive safety system, the Oris Quick Lock, which prevents any unintentional disturbance! Finally, there is a large date window at three o'clock. This watch is dressed in a black leather strap with a folding clasp.
