Background
The 556 B is the blue dial variant of Sinn's 556 line, launched alongside the 556 A and 556 I around 2003. It combines the same 38.5mm case and Sellita SW 200-1 movement with a distinctive sunburst blue dial. The pricing premium reflects the dial finish rather than technical differences.
Design
The 556 B uses applied baton indices with the same date window at 3. The blue sunburst dial adds visual depth while maintaining the 556's clean, pilot-watch legibility.
