History of the Pontiac watch:A. Kinsbergen and his three brothers launched Pontiac in Belgium and the Netherlands in 1932. Mr. Kinsbergen was also an agent for Omega and Tissot. Pontiac was registered in Bienne (Switzerland). Until the 1970s, the logo had the large P extended over the other letters. After that, the letter P was the same as the others.
