Patek Philippe Gondolo Ref. 3528 4 Rare Diamond Set 18K White Gold with Integrated Asprey Signed Bracelet, early 1970s

Dealer description — Bulang & Sons

Some vintage Patek Philippe watches have a way of blurring the line between fine watchmaking and jewellery. This particularly unusual reference 3528/4 is a wonderful example. Combining a diamond-set white-gold case, an exceptionally uncommon dial configuration and a beautifully integrated gold bracelet, it represents a fascinating and seldom-seen side of vintage Patek Philippe. Dating from the early 1970s, the 18K white-gold tonneau-shaped case measures approximately 29 × 26 mm. Two delicate rows of diamonds follow the curved sides of the case, framing a silver soleil dial with slender baton markers and elegant hands. At 12, 3, 6 and 9 o'clock, three small diamonds replace the traditional hour markers, creating a beautifully balanced and distinctive appearance. The dial configuration is particularly rare. We are aware of only one other reference 3528/4 featuring a comparable diamond-set dial, an example bearing the Khanjar emblem of Oman. Another lovely detail is that this watch was retailed by the celebrated London jeweller Asprey, as evidenced by the Asprey London signature on its clasp. Asprey was also known for supplying watches to the Omani royal family, including special pieces bearing the Khanjar emblem. A fascinating little detail in the history of this already distinctive Patek Philippe. Perhaps the most captivating element is the integrated 18K white-gold bracelet. Its finely woven construction and intricate textured finish give it an almost fabric-like appearance, flowing naturally from the case and wrapping elegantly around the wrist. The bracelet shows signs of wear consistent with its age, while retaining its wonderful texture and character. It accommodates a maximum wrist circumference of 18.4 cm. Inside, the manually wound Patek Philippe calibre 175 has been fully serviced by an experienced professional watchmaker. For us, the attraction lies in the beautiful balance between fine watchmaking and jewellery design. The unusual diamond-set dial, sculptural case and wonderfully tactile gold bracelet come together in a piece that feels elegant, individual and unmistakably vintage.
