The Heart collection pays homage to femininity, thanks to a sinuous and curved silhouette which features both a fascinating case as well as a sapphire glass that is particularly difficult to produce (which, incidentally, is found on all Franck Muller watches). The result is a must-have line that embodies the spirit of women who love elegance and beauty. The ‘heart’ is the emblem of this fascinating multi-faceted line. The Heart collection features silver, burgundy, black and blue hues. The heart is the very symbol of pure elegance. The alligator strap, which matches the dial colour chosen, emphasises the extreme delicacy of this special collection.
