Notes

The "World Time" system was invented around 1935 by Louis Cottier (1894-1966), the famous independent watchmaker in Geneva. Considered by many to be the most practical and important inventions of modern horology, his "World Time" patents were used by Agassiz and other major manufacturers in the Swiss watch industry, including Patek Philippe, Rolex and Vacheron & Constantin.
