About The Chopard Happy Diamonds 4066:
The Chopard Happy Diamonds collection is one of Chopard’s most recognizable jewelry-watch designs, known for diamonds that move freely between transparent crystals. This floating diamond concept gives the watch a playful and distinctive look, with the stones catching light as they shift with the motion of the wrist.
This ref. 4066 pairs the Happy Diamonds design with an 18K yellow gold case, diamond-set bezel, and multi-strand rope-style bracelet. The result is closer to a fine gold bracelet than a conventional wristwatch, while still carrying the signature Chopard dial and quartz movement.
This circa 1985 example is especially complete, with original outer box, inner box, certificate of origin, and 2026 service papers included. The combination of 18K yellow gold construction, floating diamonds, diamond-set details, and original documentation gives the watch strong vintage Chopard character.
