    With Patek Philippe Extract from the Archives confirming production of the present "torpédo" watch with excentred second hand, extra lever escapement, silvered dial and black enamel numerals in 1926 and its subsequent sale in July 1938.

    Patek Philippe movements participating at Observatory Timing Contests were numbered twice.

    According to the accompanying timing sheets of the Geneva Observatory, this deck watch was presented at the 1933 First Class timing contest and achieved the third price with 733.2 points. It had been prepared and adjusted by F. Moudoux, renowned for adjusting Patek Philippe's finest chronometers.

    The so-called "torpédo" mechanism is activated by depressing the button in the case band which then pushes a steel spring against the balance in order to stop it. This feature, more commonly known as "hack feature", allows the restart of the movement simultaneously with the exact time.
