Why these choices
Ostrich leg leather adds a natural grain that keeps a plain-dial watch from looking flat, and dark gray stays neutral against the Sinn's brushed steel and white or mother-of-pearl dial. The light-brown stitching is kept minimal so the texture leads.
The owner noted they like thicker straps, so we built it with more body than a flat dress strap; that suits the 556's case and feels substantial without full padding. A classic stainless buckle matches the case.
At 75/115 mm on an 18 mm buckle width, the strap centers the 38.5 mm case on a mid-size wrist with a clean tail.
