GOOD TO KNOW
• One of five special anniversary edition 3970ER made for Patek Philippe’s 2015 London Watch Art Grand Exhibition; one of only two examples that have appeared publicly
• Well-preserved in excellent condition and complete set
• Rare and coveted black dial with applied Breguet numeral 12

With over 400 exceptional timepieces on display, the 2015 Patek Philippe Watch Art Grand Exhibition was the largest overseas exhibition of the brand at that time. To celebrate this significant occasion, Patek Philippe publicly released a selection of previously discontinued pieces with special dials for the first time, reserved exclusively for their most trusted clientele. Today, watches from this landmark exhibition are regarded as trophy pieces due to their rarity and historical significance within Patek Philippe's legacy.

Launched in 1986, the ref. 3970 continued the legacy of the iconic ref. 2499, sharing its downturned fluted lugs and pump pushers reminiscent of historical models. As a modern perpetual calendar chronograph, it introduced several innovations, replacing the Valjoux movement of its predecessors with a heavily modified Lemania cal. 2310 D. The cal. CH 27-70 Q now indicated leap years, while a 24-hour hand added practical functionality.

Even a decade after the 3970 was discontinued, Patek Philippe wasn’t quite done with it. In 2015, for Patek’s 175th anniversary celebrations, the company dusted off a few leftover 3970 cases and movements to create a very limited run of special editions. The most notable were the so-called “London Saatchi Edition” ref. 3970ER-028 and ref. 3970EP-046. The 3970ER-028 consisted of just 5 pieces in rose gold (hence “ER” for Étanche Rosé) with a black dial featuring a tachymeter, dot hour markers, and a single Breguet numeral at 12.

Essentially, these watches resurrected the 3970 design 11 years after its official end, proving the model’s enduring appeal. They were assembled from new-old-stock 3970 parts and so are identical in form to a regular 3970, but with that special dial configuration and corresponding dial code set them apart.

With the setting pin, numbered hang tag, and solid caseback still in their seal, this extremely limited example of the 3970 furthermore retains its original certificate of origin and presentation box.
