The 1970s was a period when watch designers and jewellers worked closely together, blending horological innovation with bold artistic expression. As the disco era encouraged self-expression on the dance floor, watch design followed suit with a spirit of creativity and freedom. There were no rules—anything was possible—and both men and women embraced solid gold watches, often lavishly adorned with gemstones or intricate engraving. This was the age of sculptural forms and integrated bracelets. A classic example is reference 3729G, where the ‘Tubagaz’ bracelet seamlessly complements the stepped bezel of the Ellipse-inspired case. The minimalist black onyx dial, devoid of hour markers, perfectly captures the aesthetic of the decade. Movements were typically simple, as complications tended to disrupt the clean lines and sculptural elegance that defined the era. It was the design and decoration that truly mattered.

Introduced in 1976, reference 4339J is another striking example that captures the bold spirit of the maison during this expressive era. It is a rare and distinctive model produced briefly between the mid-1970s and mid-1980s. Its Art Deco-inspired design features a pavé diamond-set bezel and 18K yellow gold ornaments on the case. As indicated by the “key number 5” mark inside the caseback, the present timepiece was made by George Croisier, one of the important casemakers in Geneva. The present example is adorned with 152 diamonds, totalling approximately 2.06 carats. Exceptionally rare, only two examples have been documented in the market to date, making this the third known piece. Offered in excellent overall condition and accompanied by an Extract from the Archives, this fresh-to-market timepiece is a striking and elegant choice for those seeking to stand out on any occasion.
