The Type 21 is a very high-precision chronograph. It is equipped with a special mechanism called "fly-back" enabling to measure pre-set time with continuous or interrupted operations.This function enables to start, stop and restart the central hand telling seconds divided to the 5th as well as the hands telling minutes and hours.

The chronometer’s Start function is set by pushing the first push-button A. With a second push on this button, the central hand is stopped. A third push on the same button re-starts the chronometer hand. This enables to stop a time measurement and re-start it at the stop mark.

Zero-setting function of seconds, minutes and hours is obtained by pushing the second
push-button B.

The Fly-back device allows it to be instantly reset during the chronograph's operation by pressing the second button (B), without having to first stop the operation with the first button (A). When pressure is maintained on the second button, the hand stays at zero and only starts again when pressure is released. The device enables an aircraft pilot or ship's captain to follow instructions and change headings according to a predefined course. Once a sequence has elapsed, pressure on the button launches the following sequence.

The rotating bezel completes the sums of minutes and hours by acting as a countdown timer. For a four hour flight, the pilot enters the number 4 opposite the hour hand of the main dial, and starts the chronograph: when the hour hand is opposite the luminous 0 mark, the four hours have elapsed.

The tachometer measurement enables to know the plane speed when taking off on a short runway. As a matter of fact, if the pilot has not reached the sufficient acceleration to take off regarding a pre-set distance, he will choose to reverse the engine push in order to try to take off again safely.

History Of Type-21
Military watches have a history; they reflect intensive efforts in the quest for precision and authenticity. The watch actually had to compensate for onboard instrument failure by acting as a navigational instrument for the pilot. While conserving their precision, these chronographs already withstood extreme constraints in terms of acceleration, vibration, temperature variations and resistance to magnetic effects. By official command from the French General Staff, the House of Dodane developed the Type 21 in the 1950's. The "fly-back" function was the principal requirement in the stringent specifications then set out for the chronograph by the Ministry of Defence. The demands of various silent partners, particularly the Navy and Air Force, obliged our master watchmakers to advance still further in precision and reliability, as well as in complexity.

First condition: owning the "fly-back "function i-e the possibility to set to zero and then to restart immediately the chronometer function. The high officials o in the Air Force have imposed this condition as it was vital for pilots when they would fly over a beacon or when they had to land relying on the time given by the control tower.

Such a demand may sound odd if one thinks about the evolution and sophistication of the present electronic outfits. Nonetheless, at that time, the reliability of the clock and watch making industry was a matter of life or death, the watch had become a flying instrument capable of replacing a failing onboard device. Among other requirements from the French National Defence's specifications: an autonomy of over 35 hours, a maximum time difference of 8 seconds per any 24 hours. The difference was reduced to 0.2 seconds per minute and 0.5 seconds per half hour for chronometers. Besides the chronometer was supposed to operate at least 300 starts, stops and zero-setting in a row. Already used by the Air Force and other corps, the Type 21 was supplied to NATO forces involved in sensitive missions. In the1990's, Dodane Type 21 chronographs continued to wield their talent in Army light aviation.
