OUR TAKE
The dial is the story — a blue sunburst that goes near-black indoors and turns electric under a window. It's a 41mm pilot with a 46.5mm lug-to-lug, so it wants a medium-to-larger wrist; the two straps (Sinn silicone and Sinn canvas) cover both ends of the week. To flag honestly: a deep cut on the underside of the lower lugs (see photos), light hairlines elsewhere, and no dated warranty card. Priced accordingly.
