The watches from the 556 series are characterised by striking lines, minimalistic displays and clear readability. Fine satinised stainless-steel cases with crystal and transparent back made of sapphire crystal glass. Sophisticated dials with diamond-cut rhodium-plated hands and appliqués. These are the features that make these sporty watches so distinctive and elegant.

For the 556 I Mother-of-Pearl S edition, we created a particularly masculine design with a shimmering black mother-of-pearl dial. Mother-of-pearl is a natural product that makes each dial unique and gives the watches their individual, distinctive shine.

To ensure good readability at night, the hour and minute hands are luminous, as are the hour indices. We have also made these watches pressure-resistant to 20 bar and resistant to low pressure.
