Four companies supplied the Type 20 to the armed forces, Vixa, Breguet, J. Auricoste and Dodane. Breguet were commissioned to produce 2000 watches by the government in 1954. The specifications for the Type 20 were that the watch was accurate to at least 8 seconds per day, a power reserve of at least 35 hours, to include the flyback function and the ability to operate satisfactorily at least 300 times. Due to the use of these watches they had to be serviced regularly. The date for the next scheduled service was stamped on the case back next to the letters FG. This stood for fin de garantie, which translates to end of warranty. This watch has six dates stamped to the case back.
