Sinn 556 I B


Model: 556.0104

A fresh take on the 556

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.

The 556 I B Edition features a dark-blue, electroplated dial finished with a sunburst decoration that catches the light to reflect beautiful hues of blue. But this watch isn’t all about good looks. Sinn hasn’t forgotten the need for functionality and to ensure optimal readability at night, the indices and hour & minute hands are coated with a generous amount of Superluminova, plus, as with all of the 556 pieces, the 556 I B is water-resistant to 20 bar (200m) and resistant to low pressure. Why not freshen up your look with Sinn’s sporty and elegant 556 I B. (Our tip: this piece looks great on the fine link metal band!)
