Patek Philippe chronograph wristwatches have always been a collector’s favorite due to its elegant and timeless appeal. Dating all the way back to the 1930s, Patek Philippe introduced the ref. 130, their very first serially produced chronograph wristwatch due to the surge in request for chronograph wristwatches during the era. Incredibly successful and well-received, the ref. 130 went on to enjoy a long and prosperous production span of almost 30 years. However, with that said there were other extremely important chronograph references such as the refs. 530 (the larger counterpart of the ref. 130), 1463 (the firm’s first ever waterproof chronograph with a screw-down caseback and round “Tasti Tondi” pushers) and the 1579 (arguably the firm’s most elegant and unusual chronograph reference being the only chronograph reference with fancy “Spider lugs”).

In modern times, one of Patek Philippe’s most groundbreaking innovations was the introduction of the manufacturer’s very first in-house chronograph caliber CH 29-535PS AIG.1. The reference to be released together with the new caliber was the ref. 5170. Succeeding the large 42mm ref. 5070 (Patek Philippe’s last Lemania powered reference), the new ref. 5170 took inspiration from its elegant ancestors hence adopting a smaller case size at 39.5mm. Introduced initially in 18K yellow gold in 2010, the reference was produced also in white gold, rose gold and platinum with different dial variations for each respective metal.

The present example ref. 5170J from circa 2012 belongs to the very first model and iteration of the reference launched in 2010. Offered with the full set of accessories, the ref. 5170 is with no doubt a highly undervalued reference that has recently been discontinued, which made way for Patek Philippe’s new chronograph ref. 5172G. The present example being the very first to feature the firm’s first in-house movement will most definitely be a collectible factor. Preserved in excellent condition with extremely attractive estimates, this is one that certainly does not require any hesitation for one to leave a bid.
