I may be wrong, but I don’t feel lists of greatest Britons are drawn up as often as they once were. As it is, even when these rankings appear, the name of John Arnold (1736-1799) doesn’t tend to register. This despite the fact the Bodmin-born horologist was one of (and perhaps the most significant of) a group of 18th-century horologists who — quite literally — put Britain on the map.

It will never be humdrum, but it’s worth noting that Breguet himself managed just 35 tourbillon watches before his death in 1829.
