A very special form of wristwatch is now making a renaissance - ‘The Tonneugraph’. So it’s no surprise that the legendary Lucerne watchmaker Carl F. Bucherer is presenting the Patravi Tonneaugraph for the very first time at the Basle clock and watch fair this year.

For those of us who have a busy life, yet long for clarity and simplicity, the Tonneaugraph is the perfect solution. It combines three very useful functions; A Chronograph, a large date dial, and a power reserve meter. Each of these three functions can be read clearly, and within the intricate, multi-part case rests the automatic calibre CFB 1960 movement. The power-reserve meter has a high/low display, set in the form of a circular dial located at the six-o-clock position on the watch, that turns clockwise as the watch is wound.
