Yema Superman Heritage compatibility

Wear a smartwatch with your Yema Superman Heritage

In short Smartlet is compatible with the Yema Superman Heritage. Lug width: 19mm / 20mm - natively supported with no adapter. Installation uses the standard spring-bar system. No modification to the watch required. Fully reversible in seconds.

Yema launched the Superman in 1963 - the same year the Rolex Submariner was establishing the dive watch category. While the Swiss giants took the international market, the Superman became the dive watch for French professional divers, military frogmen, and the Cousteau expeditions. Sixty years later, the Superman Heritage revives that identity with modern specifications: 300m water resistance, in-house movements, and a case that reads as original because it is. The French watch community's loyalty to it is not nostalgia - it is earned.

  • Beschädigt oder verändert Smartlet meine mechanische Uhr?
    Nein. Smartlet ersetzt Ihr Standard-Uhrenarmband mit dem vorhandenen Federstift-System. Es werden keine dauerhaften Änderungen am Uhrengehäuse, den Hörnchen oder dem Zifferblatt vorgenommen. Der Vorgang ist vollständig reversibel und dauert nur Sekunden. Ihre mechanische Uhr bleibt unbeeinträchtigt und kann jederzeit unabhängig getragen werden, indem Sie einfach das Originalarmband wieder anbringen. Smartlet ist nach Uhrmacher-Toleranzen konstruiert und wird mit der gleichen Sorgfalt getestet, die auch in die Uhren fließt, mit denen es kombiniert wird.
