Temat w prawdzie prehistoryczny, ale w kwestii korekty historii tej jednak bardzo zacnej marki: The alarm watch CricketVulcain became especially known by their alarm watch Cricket, which was presented in 1947. 1961 the companies Revue, Vulcain, Buser and Phénix merged to form the "Manufactures d'Horlogerie Suisse Réunis SA" (MSR). During the so-called quartz crisis in the 1980s the name Vulcain quietly disappeared from the dials, the market for high-quality mechanical wristwatches collapsed. The future seemed to belong to cheap quartz watches. The manufacture Vulcain still produced their watches for sister brands within the MSR. Also when the Cricket was produced again under the name of "Revue Thommen", this happened in the studios of the manufacture Vulcain in La Chaux-de-Fonds. Reasumując RT to ani "zegarek prezydencki", ani pierwszy z alarmem a już na pewno nie producent tegoż mechanizmu.
