1970s-80s Malachite Swiss 18k Gold

A striking vintage Swiss watch from the 1970s–80s, capturing the bold gemstone and gold designs of the period. Unsigned throughout, the watch is crafted in 18k yellow gold with Swiss hallmarks and has a particularly sculptural presence despite its compact proportions.

The square case is framed by a rolled, rope-like bezel, with malachite cabochons set into the terminals above and below. A vivid malachite dial continues the stone motif, displaying beautiful natural striations and an intentionally minimal layout with a single oversized Roman numeral at 12 o’clock and slim gold hands.

Of particular interest, the case is stamped “GRG,” the maker’s mark associated with Roland-Gilbert Gaschen, a Swiss case and bracelet maker known for producing work for high-end watch and jewelry houses. While the watch itself remains unsigned, the maker’s mark adds an interesting connection to the specialist workshops behind Swiss jewelry watches of the period.

Powered by a caliber 2512-31 manual-wind movement, the watch retains its original black alligator strap and original 18k yellow gold buckle, stamped “GD Swiss .750.”

With its combination of malachite, textured gold and unusual case construction, it is a wonderfully expressive piece of 1970s–80s Swiss design with a strong jewelry-like character.
