This “One Hertz Dune” is an 18k red gold version of Gronefeld’s One Hertz 1912 Dead-Beat Seconds watch. “Dune” is added to the name and I think the new color tones on the watch really give it a new personality. This isn’t just a gold version of the One Hertz, but a different piece with a more sultry personality. Interestingly enough, this red gold version will be limited to 20 pieces, while the steel version was limited to just 12 pieces – usually the more precious the metal, the less pieces in the limited edition.
