The **155 Pilot Chronograph** is a wristwatch by [[Sinn]].

This excellent to read pilot's chronograph belongs to the range of the Bundeswehr (German military) [[chronograph]]s, which started in [[1967]] with the legendary model [[Heuer Bundeswehr]].

After [[Heuer]] had not continued the model, [[Helmut Sinn]] in the 1980s and 1990s bought discarded stocks of the Bundeswehr and after revision sold them again. Some of these watches he provided with dials showing the "Sinn" lettering. The model **Sinn Fliegerchronograph 155** is understood as a continuation of the original Heuer model. Instead with [[manual winding]] movement it was now equipped with the proven and robust [[self-winding]] movement [[Valjoux 7750]].

This edition was limited to 300 pieces and exclusively sold by the German dealer [[http://www.manufactum.de/|Manufactum]].
