A Russian watchmaker's 1.65 mm mechanical watch wins a 'watch Oscar'

Konstantin Chaykin, a Russian watchmaker, has been recognised in Switzerland, the home turf of the industry, with what is nicknamed the 'watch Oscar'. The prize is for the world's thinnest mechanical watch, which measures just 1.65 mm. That is thinner than two stacked credit cards, and it still has to hold a working mechanical movement with no battery. Prizes of this kind are rarely handed to outsiders, which is part of the appeal, along with the engineering stunt itself.
