Приветствую! Если еще актуально.
Это механизм несуществующей ныне Record Watch Co. В 60-е компания была приобретена Longines, а калибр 1958-2 был переименован в Longines 507. Одна из особенностей - дата выставляется нажатием на заводную головку. Очень удобно. Вот ссылка на спецификацию -

Судя по ней калибр выпускался в 70-е.
А вот справка по Record Watch Co.:

1916: Merger with several companies under the name Record Dreadnought Watch Co. S.A., with a broad collection of all kinds of clocks, watches, and movements. Brands and names of the involved companies continued to be used.
1949: The original name Record Watch Co. S.A. was registered again.
1960: A Record pocketwatch (calibre 435B) was the first Swiss watch to achieve wide acceptance on US railroads.
1961: Longines bought the majority interest in Record. The brand Record continued - on some watches as Longines-Record. Some Record calibres were renamed as Longines calibres.
1991: Record was closed.
