Description
A cockpit instrument for the wrist
This Yema Flygraf from circa 1970 is a distinctive French aviation chronograph, powered by the hand-wound Valjoux 7736, a robust cam-operated three-register chronograph movement. Its defining feature is the two-part logarithmic calculation bezel, conceived for flight-related calculations involving speed, distance, fuel consumption and unit conversions. Period Yema advertising presented the Flygraf as an “instrument de bord” — a cockpit instrument — aimed directly at aviation professionals.

Condition and character
Condition:
This Yema Flygraf presents with the honest wear expected from a vintage aviation chronograph of this age. The stainless-steel case shows visible signs of use, while the blue-and-white calculation bezel has developed noticeable wear that adds to the watch’s period character. The dial remains visually strong, with its distinctive three-register layout and coloured lower counter clearly preserved.
The Heart:
The Flygraf is powered by the Valjoux 7736, a hand-wound, cam-operated chronograph calibre with three registers, including a 12-hour recorder at six o’clock. Its robust and practical construction suits the instrument-like character of the Flygraf particularly well, providing the mechanical foundation for its distinctive three-register dial.
Guarantee:
This vintage Yema Flygraf has been inspected for proper mechanical operation before sale. As with any vintage chronograph, water resistance should not be assumed unless it has been specifically tested. We recommend avoiding unnecessary exposure to moisture in order to preserve the watch and its original components.
Authenticity:
This example displays the key characteristics associated with the early Yema Flygraf: the signed black dial, three-register chronograph layout, distinctive coloured lower counter and two-part aviation calculation bezel. The Valjoux 7736 movement is consistent with this generation of Flygraf. Final confirmation of originality should always be based on the physical watch, including its movement, case markings, dial, hands and other components.

More than a pilot’s chronograph
What made the 1970 Yema Flygraf a genuine aviation chronograph?
The Flygraf earned its aviation credentials through function rather than military association. Period Yema advertising from 1970 presented it directly to pilots, radio operators and mechanics as an “instrument de bord” — a cockpit instrument. Its hand-wound Valjoux 7736 chronograph measures elapsed time, while the two-part logarithmic calculation bezel was designed for practical calculations involving speed, distance, fuel consumption and unit conversions. Together, these functions made the Flygraf a purpose-built aviation instrument rather than simply a chronograph styled to look like one.
