Patek Philippe never disappoints! In the antique Patek Philippe watches from the 1960s and 70s, square watch cases are very rare. The Ref.3859 we are sharing today comes from the 70s, with a three-layer case and an integrated woven bracelet that exudes a vintage charm. With dimensions of 27 * 28mm, it is perfect for wearing both in the past century and today, and the square stepped case exudes elegance on a man's wrist. The 18K gold sigma dial is in excellent condition, with no signs of oxidation visible to the naked eye, Patek Philippe signature at 12 o'clock, sigma dial signature at 6 o'clock, and the striped design on the dial exudes a strong vintage charm; dauphine gold hands, 3, 6, 9, 12 bar indices, comfortable balance. The striped dial perfectly matches the stepped case, showing taste, elegance, and confidence. 18k original integrated bracelet, 185cm long, with a three-stage original clasp. The watch is equipped with Patek Philippe's in-house 177 movement, with 18 jewels, providing approximately 40 hours of power reserve when fully wound.
