The watches that mostly made Patek Philippe brand famous are certainly those belonging to the chronograph family with perpetual calendar and moon phases. Constantly in production until the present day, this dynasty was born in 1941 with the legendary 1518 replaced only a few years later by the equally iconic 2499 (in 1950). This model remained in production for about 35 years when Patek decided to renew the style of this special object giving rise to the reference 3970. Introduced in 1986 until around 2004 (when it was replaced by 5970 and later by 5270) what distinguished it from the previous model was the Lemania movement instead of Valjoux and the size that fell to 36 mm in diameter. Produced in 3 different series, the Patek Philippe 3970/2 offered here is part of the third and last series launched since 1989. Entirely made of platinum with a bracelet also in platinum with a delicate woven pattern, as certificated by the extract that confirms its production in 1993, this series presented a solid screw back able to guarantee waterproofing. Extremely well preserved, this watch is equipped with a very elegant argentè dial with applied baton numerals. The two windows for day and month are positioned slightly above the signature while the date surrounds the sundial with the fascinating moon phases display. On the sides, at 3 and 9 o’clock, the other two sunken counters. Although this reference is still considered young, it has already reached a state of absolute prestige among the perpetual calendar chronographs with moon phases and is now a must-have for every collector of complicated wristwatches.
