Quick TakeThe Sinn 556 I Mother-of-Pearl S is where rugged engineering meets subtle artistry. The satinized steel case speaks of pure functionality. It's that kind of watch you know can handle anything, yet the black mother-of-pearl dial throws in an unexpected twist. Each shimmer is completely unique – it's like wearing a sliver of the midnight sky. The precisely applied indices and luminescent hands aren't just practical; they give the dial a crisp, almost architectural quality. And then you get the smooth sweep of the SW 200-1 movement, visible through the sapphire case back, it is the reliable heart of the entire operation. It's that contrast – the precise German engineering against the organic, ever-changing beauty of the dial – that makes this watch so captivating. This watch feels solid and ready for anything, the mother of pearl is mesmerizing, and the movement is just the icing on the cake. The 556.0105 model is ready for anything.

DescriptionThe Sinn 556.0105, part of the distinguished 556 series, is characterized by its robust construction and legible design. Central to its architecture is the 38.5mm diameter case, meticulously crafted from satinized stainless steel. This finishing process provides a subdued, matte appearance while enhancing the metal's resilience. The case thickness measures 11mm, a dimension contributing to the watch's comfortable presence on the wrist. A screw-fastened case back and a screwable crown contribute towards achieving the watch's substantial water resistance rating, standardized at 20 bar according to DIN 8310. Additionally, the design is engineered to be resistant to low-pressure environments. The total weight of the watch head, excluding the strap, is a precise 65 grams, demonstrating an efficient balance between robustness and wearability. The transparent case back allows for unobstructed viewing of the movement. Sapphire crystal glass features prominently, this is employed both for the front crystal and display back. Anti-reflective coating on both sides of the front crystal and the interior of the case back maximizes visibility under varied lighting conditions, minimizing glare and reflection.

The dial, a defining feature of this model, showcases a shimmering black mother-of-pearl surface. This naturally sourced material ensures that no two dials are exactly alike, imparting a level of individuality to each timepiece. Rhodium-plated, diamond-cut appliqués, applied manually, serve as hour markers. The incorporation of luminescent material on the hour and minute hands, as well as the indices, facilitates low-light readability. Powering the watch is the SW 200-1 self-winding mechanical movement, equipped with a seconds stop function for precise time-setting. This movement incorporates 26 bearing jewels. The movement's operational frequency is 28,800 semi-oscillations per hour (4 Hz). It also confirms with DIN 8309, which outlines a watches anti-magnetic features. The band lug width is a standard 20mm, allowing a lot of versatility.
