The Sinn 556 I B Leather 556.0104 embraces the soul of Sinn very well, by combining a less is more design, with practicality and a very high quality level.

The watch has all the basics right, such as 200m water resistance, sapphire glass with an AR coating, the quintessential Sinn-style leather strap and a solid SW 200-1 mechanical movement.  On your wrist it will be a very refined presence, while the quality will ensure a reliability and practicality. And that's how the 556 has built such a solid reputation as a hugely comfortable, understated watch that shines especially due to it's modest 38.5mm diameter and mere 11mm thickness.
