Collectors had their eyes on Cartier at the $1.2 million Heritage Auctions Signature Timepiece sale on Dec. 7 as a fantastically rare Diamond, Jade, Pearl, Coral and Rock Mystery Clock brought $155,350 and a gorgeous Silver, Gold Jadeite and Pearl Four Dial Eight Day Lamp-Form Desk Clock, from the Collection of the American Red Cross, brought $65,725. All prices include 19.5% Buyer's Premium.

Any Mystery Clock is hotly pursued when it comes on the market, which is a rare enough event in-and-of itself, and a few determined collectors weren't going to let the opportunity to acquire such a piece get away without a fight. The result was spirited bidding and the final $155,000+ price, which more than doubled the low estimate of $70,000 for this Art Deco inspired masterpiece.

The number two lot in the auction, a very fine and exceedingly rare Cartier Silver, Gold, Jadeite and Pearl Four Dial Eight Day Lamp-Form Desk Clock, No. 1611, circa 1930s, came from the Collection of the American Red Cross and is one of only three examples known to exist.

No conversation about fine timepieces is complete without talking about Rolex, perhaps the most recognizable high-end watch name in the world. A Rolex Diamond & Gold President with Meteorite Dial, Ref. 118388, circa 2007, was the top lot for the legendary watchmaker in the Heritage Auctions' event, as it brought $26,290. Close on the heels of the Rolex President watch was a rare and always popular Rolex Reference 6263/6262 Steel Daytona Cosmograph, circa 1970. This beautiful example was hotly contested between erudite collectors before arriving at $21,510.

An exquisitely crafted Patek Philippe Rare Ref. 2526 Gent's Gold Automatic Wristwatch With Enamel Dial, circa 1958, received a good deal of attention before bringing $21,510 to tie for the fourth highest lot in the auction, while a rare and very fine F.P. Journe Platinum Octa Automatic Lune Chronometer No. 051-AL, circa 2007 came in just behind it with a highly respectable final price of $21,110.
