Reference 5970 was introduced to the market at the Basel Fair in April 2005 and replaced the celebrated reference 3970. The model immediately enjoyed great popularity amongst collectors and was available in white gold or pink gold only until 2007 when the production of these two versions ceased. Reference 5970 in yellow gold was in production only in 2008. Since 2008, the model was available exclusively in platinum.
At the 2011 Basel Fair, the reference 5970 was replaced by the smaller reference 5270 which additionally has a day/night indication on the dial, as well as a separate leap year cycle and is equipped with the in-house caliber CH 29-535 PS Q.
Reference 5970 is the last perpetual calendar chronograph of the company featuring the Geneva seal on the movement as Patek Philippe began stamping their movements with the Patek Philippe Seal from mid-2009 as a new quality benchmark for its mechanical timepieces. Despite having been manufactured in recent years, reference 5970 is already today considered a great classic and will not only provide enormous pleasure on its future owner's wrist, but will also be a pillar in any collection focusing on Patek Philippe's history of complicated wristwatches.
To the best of our knowledge the present watch has never before been offered in public. For an example in yellow gold, please see Lot 101 in this sale.
