But there's still something rather appealing about Urwerk’s UR-1001 Zeit Device (£240,000) – and it's not just seeing the Genevan duo's prowess appear in a larger format than usual.
As part of the science of measuring time, it takes the 'generation-lasting watch' concept beyond any sensible limit: the UR-1001 Zeit Device marks not just hours and minutes, it is set up to record the months, years, centuries and millennia, too. As Felix Baumgartner – one of Urwerk’s founders – explains, designing a pocket offered "a larger playground for our imaginations".
