Not sure that we have a record of this booklet/guarantee yet? It seems to show authorized dealers from around the world. Very interesting, they even had an agent in Fiji !!!
Curious remark:
"The Compur trademark was registered in 1934, and the following year a whole range of chronographs was launched, proudly exhibited at the 1935 Basel Fair. They all had two pushers, and were among the first, along with Breitling and Angélus, to feature this improvement. All cases are of high quality: gold or steel, whereas stainless steel, very expensive at the time, had only been introduced into Swiss watchmaking a few years earlier. From then on, the Universal Watch Genève brand appeared most often on dials, even though the company’s official name was still Perret & Berthoud."
