I am not so sure if the US presidents (Eisenhower + Nixon) were wearing a cricket watch made by RT or by Vulcain. Probably the latter. But yes, RT did (or does??) make a cricket watch, largely using the AS movement also found in Oris and Maurice Lacroix wrist mechanical alarm. RT was selling them in the early 1990's (maybe earlier). You could get one from Hour Glass Singapore for about S$ 1,200 at that time. I remember because I bought one in 1992 when I was in Singapore at that time.
