When Patek announced their entry into the Only Watch 2013 auctions, our jaws dropped. Ther Ref. 5004T is certainly a collector’s piece. A perpetual calendar with a titanium case is a rare combination.

Only Watch is a charity auction that is held bi-yearly in Monaco with entries from numerous manufactures such Vacheron Constantin, Patek Philippe, Hublot, Chanel, Breguet etc. It is a chance for the manufactures to show off their amazing and rare entries into the auction, but more importantly, to work together to raise funds for muscular dystrophy research. The bidding room will be filled with the who’s who of society, rest assure they have very deep pockets.

The Patek Ref. 5004T is a split second chronograph perpetual calendar. Discontinued in 2011 when it was repaced by the Ref. 5204, the 5004 was a key reference piece for Patek. This one is cased in titanium and even though Patek has produced some titanium cases before (only 3), and is a one-of-a-kind, this is the only example of the Ref. 5004 in titanium produced exclusively for Only Watch. Another Patek watch, the 5712T was produced also for Only Watch in 2007 and sold for a whopping AUD$800,000.

At 36.7mm it is on the conservative side and the key feature is the dial. It may not be obvious but it is made of solid gold and engraved by hand to look like carbon fibre. Matchnig the dial is a calf skin embossed with a carbon fiber pattern. It looks very much like a sports watch.

The movement is a Patek CHR 27-70Q caliber that is highly decorated but based on a Lemania movement with a perpetual calendar added onto it. Not a full in-house movement, that’s almost blasphemous. However this can be overlooked adding a perpetual calendar complication to a Lemania base no no easy feat. The final hammer price will also show that collector’s will not care about this, we expect the price to reach over AUD$1 million.
