Louis Erard Watch Heritage Open Fume Blue 60287AA85.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, the purity of the Swiss Jura and more precisely the magical L Heure Bleue, a blue sunburst dial that shades off progressively to black on the contour gives depth and intensity to this characterful Heritage.
