If you are in New York City in the middle of December, you might want to know about Christie’s “Important Watches” auction. The Gordon Bethune Collection of Fifty Exceptional Wristwatches is a rare medley of top-quality timepieces, including representation from Patek Philippe, Rolex, Vacheron Constantin, and Cartier.

The former chief executive officer of Continental Airlines is a noted watch connoisseur. His collection, estimated at $3 million, is the keynote of the day-long auction to be held on December 14, 2012.
