When we slap a watch on our wrist, we hardly ever give a thought to the accuracy of tell-keeping. While some watches like the Casio G-Shock has atomic clock synchronization for accurate time-keeping, URWERK AMC Clock and Watch System takes precision time-keeping to a whole new level.
Introduced earlier this year and recently awarded the prestigious Prix de l’Audace (a new award of Geneva’s Grand Prix d’Horlogerie), one of the three URWERK AMC systems is now available for sale in New York for a cool $2.9 million.
Hefty price, no doubt, but the price isn’t just for a timepiece. It is for a system comprising of a master slave clock and wrist watch system, in which an atomic clock, through a complex mechanical linkage, would wind, set and regular an URWERK watch that rests in the a cradle in the 35 kilograms (77 lbs) solid aluminum case – the atomic clock itself.
URWERK AMC Clock and Watch System drew its inspiration from horological legend, Breguet’s sympathique clock systems which pioneered the concept of a fixed-position master clock that sets and regulates a portable satellite watch all without intervention by a watchmaker.
