Sinn 556 I Pearl S


Reference: 556.0105

A sophisticated and elegant timepiece

The timepieces from Sinn’s 556 series are characterised by striking lines, minimalistic displays and clear readability. The refinement continues in the fine satinised stainless steel cases with sapphire crystal case fronts and transparent, exhibition case backs made of sapphire crystal glass. Sophisticated dials with diamond-cut, rhodium-plated hands and appliqués complete the streamlined and understated look. Together these features make these sporty watches both distinctive and elegant.

Sinn’s 556 I Mother-of-Pearl S Edition, features a distinctive, black, mother-of-pearl dial. Mother-of-pearl is a natural product that makes each dial unique, giving each watch an individual character and ensuring no two pieces are identical. The depth of the dial contrasts strongly with the indices and hands that have the additional treatment of Superluminova for optimal readability. As with all 556 pieces this model is pressure-resistant to 20 bar (200m) and resistant to low pressure making the 556 I MOP S as reliable as it is attractive. This is a striking, everyday watch for someone who appreciates quality watchmaking and subtlety of design.

Our Tip: team this piece up with a soft grey leather or black cordovan band for a more dramatic effect.
