Flying Officer

Flying Officer

The “24-hour clock” has a special place in the big family of chronographs. The division of the face was not for fashion purposes, but due to the need to visually track the hours throughout the day. Particularly in air traffic with its comparatively fast change of locations, with the beginning of long-haul flights to faraway corners of the earth, in the 1960s pilots and navigators developed a predilection for chronographs with 24-hour displays. Consequently, all over the world they could directly relate to the reference time used in international air traffic.

We have brought back this legendary chronograph. Now this chronograph is equipped with the modern design of the robust manual winding calibre ETA/Valjoux 7760, the production of which was discontinued back in 2005. It became necessary to extensively redesign this chronograph movement so that it as far as possible resembled the face of the Flying Officer. The four precision conversion parts specially designed for this watch were a true micromechanics challenge for design and manufacture. The movement has been embellished with Geneva Stripes, blued screws and the corporate logo.

The stainless steel case manufactured in Germany has a diameter of 37.5 mm. In keeping with the current requirements of a modern case, from the side the case shape looks different from the original. Whereas in the 1960s the nickel-plated cases usually featured a highly domed plastic crystal and a highly domed snap-in back, the current three-part stainless steel case has a slightly domed sapphire crystal that is anti-reflecting on the inside, as well as a screwed back with a sapphire crystal.

The final production batch of this watch has been completed, which means this is the end of this limited series.
