Introduction
Launched in 1998, the Patek Philippe Chronograph ref. 5070 is an incredibly important milestone within Patek Philippe’s catalog of chronographs thanks to its status as their last chronograph to utilize a third-party movement. Powered by the manual-wind cal. CH 27-70, the ref. 5070 uses the Lemania cal. 2310 as its base, a practice that the ref. 5070 ended in 2010 following its discontinuation. An elegant watch inside and out, the ref. 5070G that we have here features a large 42mm 18kt white gold construction with a unique stepped design throughout its case with a stepped bezel flowing onto its stepped lugs, which add an architectural aesthetic to the timepiece. Boasting a stunning silver dial with sunken subdials in a bi-compax arrangement and applied Arabic numerals, the ref. 5070G is a true monochromatic masterpiece that is believed to have been produced no more than 1000 times by the Genevan giants.

THE DIAL
Featuring a silver dial with applied Arabic numerals and a bi-compax layout with two sunken subdials at 3 and 9 o'clock, the ref. 5070's display is thoughtfully designed, much like its large 42mm white gold case that continues the dial's stepped design across its bezel and lugs.

THE MOVEMENT
An important watch in the evolution of Patek's chronograph offerings, the ref. 5070 was the last Patek to be offered using a third-party chronograph movement, with its cal. CH 27-70 using the Lemania cal. 2310 as its base, an iconic movement throughout the world of horology.

TIMING MACHINE READOUT
This reading was taken (crown down) with a ONEOF Accuracy Boutique Edition timing machine at time of cataloging. It is provided as a courtesy only, and shall not be construed as a warranty or guarantee of any kind. Please refer to our terms and conditions of sale for more information.
Condition
The watch is in near-mint condition. The white gold case shows very light signs of wear, with crisp hallmarks on the backs of the lugs. There is some oxidation visible on the pushers. The dial and hands are like new. It is fitted with a black alligator Patek Philippe strap and a white gold deployant clasp, and is accompanied by a spare brown Patek Philippe alligator strap, inner and outer boxes, original certificate, booklets, wallet, and hangtag. Please note that the front of the box shows some minor damage.
Please Note: Due to CITES considerations, if the watch is to be shipped outside of the USA, the exotic skin strap will have to be removed.
Our Perspective
The 5070G is such a statement — 42mm of pure chronograph goodness, but still classic thanks to the stepped case and Lemania-based caliber. White gold keeps it under the radar compared to yellow or rose. Short production and great design make it a modern icon.
