Quick TakeThe 556 I RS isn't just a watch; it is a statement of purpose, a testament to restrained, purposeful design. The crisp, glossy black dial, punctuated by that electrifying red second hand, feels like pure focus, a distillation of timekeeping to its absolute essentials. Beneath that anti-reflective sapphire lies the steady pulse of the SW200-1, a workhorse you can admire through the exhibition case back. This German-made instrument, with 20-bar water resistance, is more than capable, but its magic resides in the absence of excess. Every detail, from the satinized steel to the lumed hands, contributes to a sense of unyielding clarity. It feels like a piece of precision equipment made beautiful by its very function. The 38.5mm case diameter hugs the wrist without any unecessary bulk. It is balanced and sleek.

DescriptionThe Sinn 556 I RS, identified by its product number 556.0106, is meticulously constructed around a satinized stainless steel case. This case measures 38.5 mm in diameter and 11 mm in thickness, offering a balanced presence on the wrist. The case incorporates a screw-fastened back and a screwable crown, essential elements contributing to its impressive water resistance. The design meets the technical specifications for water resistance, as defined by the DIN 8310 standard. As a result, the watch is rated for water and pressure resistance up to 20 bar, along with being certified low-pressure resistant. The use of satinized stainless steel, throughout, underlines a focus on durability and a tool-watch aesthetic, diminishing unwanted reflections. A double-sided, anti-reflective sapphire crystal protects the dial.

Powering the 556 I RS is the Sellita SW200-1, a self-winding mechanical movement. This caliber features 26 bearing jewels and operates at a frequency of 28,800 semi-oscillations per hour (4 Hz), ensuring precise timekeeping. The movement includes a seconds stop function (hacking) for accurate time setting. The watch has anti-magnetic properties compliant with DIN 8309 standards. A transparent case back, made from sapphire crystal with an interior anti-reflective coating, showcases the movement. The dial is a glossy black, creating a stark, legible backdrop for the indices and hands. Both the indices and the hour and minute hands are coated with a luminescent material, improving readability under low-light situations. The distinctive red second hand is a defining feature. The watch displays hours, minutes, and seconds, along with a date window. Band lug width is 20mm. The piece's weight, absent its strap, totals 65 grams.
