Patek Philippe 3970EJ-029 Perpetual Calendar Chronograph 18K YG Black Dial RARE UNWORN

The Patek Philippe 3970EJ‑029 is a supremely rare variant of the celebrated 3970 perpetual calendar chronograph, introduced circa 2009 in 18K yellow gold with a striking black dial featuring a Breguet numeral at 12 and tachymeter scale. Powered by the manually wound Caliber CH 27‑70 Q, this watch continues the lineage of Patek’s most revered grand complications, succeeding the legendary reference 2499. Its 36 mm case, crafted in precious yellow gold, preserves the timeless proportions that collectors prize, while the black dial adds dramatic contrast and exclusivity—reportedly only around five examples were made, with this being the only one known to the market. The watch includes full calendar displays, moonphase, 24‑hour and leap‑year indications, all arranged with Patek’s signature clarity and balance. Though a modern release, the 3970EJ‑029 embodies the refinement and technical excellence of Patek’s golden era of perpetual chronographs, making it a cornerstone for serious collectors seeking both rarity and horological pedigree. Unworn with Patek Philippe box, additional solid case back, setting pin and papers dated 2009.
