A 1970 Longines Ref. 3066-528 featuring a minimalist design centered around a single diamond hour marker at twelve o'clock, creating one of the more unique dial configurations of the era.

The 10k gold-filled oval case houses an original matte black dial, a particularly desirable feature as many examples found today have been refinished. The original dial has aged over decades to create a unique texture that resembles the raw, organic surface of dark volcanic stone. A genuine diamond is set within a stylized arrowhead setting at twelve o'clock, with no other hour markers present. Gold pencil hour and minute hands are paired with the minimalist dial.

Powered by the Longines Caliber 528 manual-wind movement. Service history is unknown, but it is running well.

The watch presents in good overall condition. The case shows oxidation from age, while the case, crystal, and dial have scratches and scuffs consistent with decades of wear, but no major damage.

Paired with a black Hirsch leather strap.
