The most expensive watch in the world: Indeed, this was the advertisement of the 1979 boldly introduced Piaget Polo -- the essence of a braceletwatch. The 1982 top-model with CHF23'150 (Swiss Francs) and thus the most expensive icon in the '82-catalogue was the bicolor (white- & yellowgold) with Onyx- & matte-dial.

The photo shows the watch (left, produced in 1981) and in the 1982-catalogue.
