Quick TakeThe Sinn 856 is the distillation of pure function poured into the form of a wristwatch. It's like having a cockpit instrument strapped to your wrist – bold numerals jump off the matte black dial, promising clarity at a mere glance, no matter the lighting conditions. The TEGIMENT-hardened steel case laughs in the face of daily wear and tear, while the Ar-Dehumidifying Technology makes you want to check the forecast for fog, just to taunt it. With 20 bar water resistance, and strong magnetic field protection, it doesn't demand babying, or coddeling. This isn't a piece of jewelry, it's a partner in crime, ready for anything, shrugging off magnetic fields and whatever else your day throws its way. The 856 is the confident whisper of "I got this" on your wrist. And the cleanly integrated silicone strap? It's the final touch on this understated, ready-for-anything, horological tool.
DescriptionThe Sinn 856, reference 856.011, represents a highly functional timekeeping instrument. Its design takes direct cues from Sinn's cockpit navigation clocks, prioritizing legibility and durability. The 40mm case is constructed from bead-blasted stainless steel and incorporates Sinn's TEGIMENT Technology, significantly enhancing its scratch resistance. This case houses a matte black dial with oversized Arabic numerals and indices, all coated with a long-lasting luminescent material. Similarly, the hour and minute hands feature this luminescent coating, maximizing visibility in low-light environments. The watch's case back is screw-fastened and nickel-free, while a sapphire crystal with anti-reflective coating on both sides protects the dial.
Powering the 856 is the SW300-1 self-winding movement. This mechanism features 25 bearing jewels and operates at a frequency of 28,800 semi-oscillations per hour. It includes a seconds stop function for precise time setting. The movement is anti-magnetic as per DIN 8309. Integrated Sinn technologies further enhance the watch's performance. Ar-Dehumidifying Technology improves functional reliability and minimizes fogging, and Magnetic Field Protection shields the movement from magnetic fields up to 100mT (80,000 A/m). The watch meets DIN 8310 standards for water resistance, confirmed to 20 bar, and it is also low-pressure resistant. The overall case thickness measures 11mm, with a band lug width of 20mm. The weight of the watch head, excluding the strap, is 70 grams. The display features hours, minutes, and seconds, along with a date display. This configuration presented features a black silicone strap, fully integrated into the case's design, which secures with a small, bead-blasted stainless steel folding clasp itself reinforced using TEGIMENT Technology.
