Horological Meandering

Graham always had the chronograph trigger but also AP, Invicta and Olympics timers [photos inside]

 

Graham made the chronograph trigger a feature of their design but the same thing has been tried by many watch makers including for the Olympic Games, Audemars Piguet Survivor, Invicta, Panerai etc...
