The appeal of a luxury timepiece has little to do with being able to tell the time. They are signifiers of status, wealth and taste (or the lack of it) and the thousands or tens of thousands of dollars/pounds/euros that they cost can be justified to some extent by the use of precious metals and gemstones, or the history of hundreds of years of artisanal craftsmanship that some brands possess. Then there is a whole other level of horology that transcends even these considerations. Where "value" is judged in a similar way to modern art. Where timepieces are created in strictly limited numbers around a unique conceptual design using cutting-edge materials and extraordinary mechanical skill. Urwerk is a Swiss watchmaker that has prospered at these lofty heights for ten years and its latest creation admirably demonstrates the attributes required of these astonishingly expensive mechanical masterpieces.
