Sinn 556I - pleased with my purchase. Wanted a single watch to wear for everything. This watch is perfect for me. It is waterproof, solid, rugged, but smart enough for work. The 38.5mm with relatively short lugs fits my 6.75 inch wrist perfectly. The black dial is crystal clear and dark. The case and bracelet are very nice. Only improvements would be bigger hour hand and if that watch case was slightly slimmer, brighter line, double line marker at 12. The watch feels in the same league as more expensive watches like Tudor black bay, IWCs, omega seamaster etc but half the price. It also has a military feel, a mix of pilot and field watch. The purchase was no nonsense, it arrived within 48 hours, securely packaged. Thank you.
