The Double Heart Beat Black Beauty is an exquisite addition to the Double Heart Beat Collection. Frederique Constant passionate depiction of two hearts joined and beating is now surrounded by shimmering mother of pearl surrounded by a ring of diamonds. Unveiled in 1994 when mechanical watches for women were a rarity, Frederique Constant wanted to show the world that its Double Heart Beat Watch was mechanical. Thus they craft an aperture above the balance wheel which rotates clockwise and counter clockwise upon its axes in a large ruby jewel. The rotation is controlled by the hairspring, which coils and uncoils unabated. This is the heart of a mechanical watch framed in the Double Heart Beat by an open heart aperture... and this heart actually feels for others. $50 of every Double Heart Beat timepiece sold will be donated to the International Heart Foundation.
