Quick TakeThe Sinn 556 I is a no-nonsense, tool-watch marvel. Don't be fooled by the minimalist, glossy black dial – this German masterpiece is all about rock-solid engineering and legibility. It is the kind of ticker that whispers quality. It is not shouting for attention. You have the rock solid Sellita SW200-1 movement beating inside, visible through the sapphire crystal case back. The satinized stainless steel case, water-resistant to 200 meters, speaks of adventure, but the 38.5mm size and clean lines keep it grounded and sophisticated. The luminescent hands and indices are the icing on the cake that make sure you can read the dial, no matter if you are in bright sunshine or at night. Forget flash; this watch is all about function paired with an understated and captivating elegance.

DescriptionThe Sinn 556 I, identified by its reference number 556.010, is meticulously constructed with a focus on durability and precision. Its case, crafted from satinized stainless steel, measures 38.5mm in diameter and 11mm in thickness. The design provides substantial presence without unnecessary bulk. The solid, screw-fastened case back is made of sapphire crystal glass that is anti-reflective on its interior, which ensures a clear view of the mechanical workings within, while contributing to the overall structural integrity. The band lug width measures a standard 20mm. The watch's dry weight, excluding the strap, is precisely 65 grams. The screw-down crown assists the watch in achieving its rating.

Powering the timepiece is the Sellita SW200-1, a self-winding mechanical movement. This caliber incorporates 26 bearing jewels, enhancing its longevity and reducing friction between moving parts. It operates at a frequency of 28,800 semi-oscillations per hour (4 Hz), providing a smooth sweep of the second hand. The movement also has a seconds stop function (hacking) allowing for accurate time setting. The watch has a resistance to magnetic fields, conforming to DIN 8309 standards. Functionality is streamlined to essential timekeeping: hours, minutes, and seconds, supplemented by a date display located. The dial, finished in a glossy black, features indices and hour/minute hands. Both the dial and hands are coated with a luminescent material for optimal visibility in various light conditions. The front crystal is constructed from sapphire crystal glass, treated with an anti-reflective coating on both the interior and exterior surfaces to minimize glare. The watch meets the DIN 8310 standards and is rated water and pressure resistant to 20 bar, including resistance to low-pressure environments.
