Historical Horology: A Little Bit about Frédéric Piguet
Frédéric Piguet has as their claim to fame (well, at least one of their claims) for having produced what was, at the time, the thinnest hand-wound chronograph movement in their Calibre 1180. First introduced in 1987, the 1180 measured in at only 3.95 mm. This was a risky move at the time, as quartz watches were still all the rage at this point.
The move, as it turns out, was quite a prescient one. Not only have mechanical watches had a comeback, the 1180 has become the basis for many other brands’ chronographs, especially once the automatic version (the calibre 1185) was introduced.
