How Time Flies: A small gilt-bronze travel clock used by Napoleon during his Egyptian military campaign fetched a record $509,000 at an auction of historic timepieces Sunday in Geneva. Napoleon bought the clock 25 days before embarking for Egypt in 1798. He exchanged it for another on his return, “because it suffered from sand and perhaps the horses and dromedaries,” according to the sales ledger of the Swiss clock company Breguet.
