Hourglass - Blue EditionView text
A limited-edition Hourglass in 10- and 60-minute sizes, resulting from a collaboration between HG Timepiece and De Bethune. As no pure blue metals exist to plate the nanoballs, they are coloured by flame-bluing, a precise and complex process engineered by Swiss watch firm De Bethune.
