This watch however comes at a price hefty enough for the ordinary mortal to afford, and that’s $410,000 as shown by the price it fetched at a recent auction.

The La Clef du Temps Tourbillon Watch is a limited edition watch with only 24 pieces. The watch is powered by a hand-winding mechanical movement with a Swiss level escapement and a vertical tourbillon. It boasts of two crowns, one for winding and another one for setting.
