Louis Erard Watch Heritage Open Fume Green 60287AA89.BAAC82. The very essence of a timepiece, hours, minutes and seconds, can be made even more remarkable, as Louis Erard shows with this creation. The eye lingers at 12 o clock, where the openwork dial allows a glimpse on the automatic movement below. Inspired by nature and the purity of the Swiss Jura, a green sunburst dial that shades off progressively to black on the contour gives depth and intensity to this characterful Heritage.
