We see very few 18ct yellow gold vintage Subs, and this one is a real beauty. The matte charcoal "Feet First" dial is in pristine condition, with nicely aged Tritium lume plots and crisp gold text flashing across the dial. The bezel insert has aged to a beautiful cool grey tone that contrasts the warm gold hues perfectly. Fitted to a grey Nato strap, this rare solid gold 1680/8 doesn't just look incredible in the sunshine, but is a superb little investment too. Waterproof to 200m.
