Sinn 556 Owner Review : Accomplished, robust and elegant

I have only known the Sinn brand for a couple of years. I had indeed missed it but by looking at more and more watch content the brand has established itself in my mind as a reference of robustness and quality. I am very attracted to tool watches especially military type and the reference 556 had been making me dream for a while. I opted for the magnificent blue dial of the 556 I B because while being a simple watch it can still be dressed up. The Sinn steel bracelet is incredible. The links are secured using rivets that must be unscrewed with 2 small Allen keys supplied with the watch. Just a little more complicated than a classic system with the assurance of the robustness of the link in addition. The movement is visible through the case back with its oscillating weight marked with the Sinn logo of the most beautiful effect. Thanks to its screw-down crown the watch is water-resistant up to 200m, as well as a diver. The movement seems very precise to me so far. It is a Sellita SW200-1 and the case is anti-magnetic. Everything is there to make this timepiece an essential tool for everyday use, with a welcome touch of elegance provided by the galvanized dial that goes from blue to purple depending on the lighting.
