A clock sealed in a block of Baccarat crystal, powered by temperature fluctuations. Well, if this does not sound strange enough, the clock is a result of collaboration between Jaeger-LeCoultre and famed designer Marc Newson to commemorate the clock’s and its engine’s ‘80th‘ anniversary. If the clock passed your attention, its mainspring gets winded through a mixture of gas and liquid ethyl chloride that expands and contracts when the temperature goes up or down. Sounds impressive, looks impressive. [via]
