Quick TakeThe Sinn 856 S UTC is a no-nonsense, get-it-done kind of watch. It’s the trusty sidekick you want when navigating complex situations, whether that means crossing multiple time zones or just making it through a hectic week. The blacked-out, Tegimented steel case means business, and the stark white-on-black dial is all about readability. Forget delicate frills; this watch screams functional. With its 24-hour hand (doubling as a nifty compass), you're prepared for anything, and thanks to the impressive anti-magnetic shielding, the movement inside keeps ticking accurately no matter what electromagnetic chaos you encounter. The dehumidifying technology is like a built-in weather controller, keeping the internals pristine. It’s a tool, pure and simple, elevated by some seriously smart engineering. This Sinn says "I'm ready," without uttering a word. The date at the 4 position.
DescriptionThe Sinn 856 S UTC, reference 856.020, represents a purpose-built instrument designed for optimal legibility and resilience. At its core, the watch is powered by an SW 330-1 self-winding movement. This mechanism incorporates 25 bearing jewels and operates at a frequency of 28,800 semi-oscillations per hour, providing a smooth sweep of the seconds hand. A seconds stop function is included, allowing for precise time setting. The movement itself is shielded to resist magnetic fields, fulfilling the anti-magnetic requirements as defined by DIN 8309 standards, safeguarding against fields up to 100mT (80,000 A/m). The movement's specifications reflect the current manufacturing standards at Sinn's facilities in Frankfurt am Main; however, minor deviations may exist in available stock due to ongoing technical advancements.
Encasing the robust movement is a 40mm diameter case constructed from stainless steel, enhanced with a black hard coating applied on a TEGIMENT technology basis. This surface hardening treatment substantially increases scratch resistance. The case thickness measures 11mm, and the lug width accommodates a 20mm strap or bracelet. The case back is securely screw-fastened and is fabricated without nickel, minimizing potential skin irritation. The crown, crucial for adjusting time and the second time zone, is screwable, contributing to the watch's impressive water resistance. The 856 S UTC is certified water and pressure-resistant to 20 bar, exceeding the technical stipulations of DIN 8310, and it's additionally resistant to low-pressure environments. Protection for the matte black dial is a sapphire crystal, treated with anti-reflective coating on both inner and outer surfaces, minimizing glare. Sinn's Ar-Dehumidifying Technology is built in and improves working reliability plus prevents misting. The watch weighs 70 grams without any attached strap.
