The 857 UTC series pilot watches unite all our core watchmaking competencies: these are instrument watches with a consistently functional design which honour the tradition of our navigation cockpit clocks.
The features include Magnetic Field Protection of up to 100mT (=80,000 A/m), Ar-Dehumidifying Technology and pressure resistance of up to 20 bar. The pilot's bezel and the second time zone on a 24-hour basis make these watches perfect, all-purpose instruments.
The stainless steel pilot's bezel with minute ratcheting can be rotated on both sides and features a special mechanical system developed by Sinn to protect against loss. Like the case material, the base of the bezel is tempered with TEGIMENT Technology. The labelling is silver on an inset, black anodised aluminium ring to ensure optimal scale readability. A luminous triangle serves as the 0 / 60 minute mark. The rotating pilot´s bezel can be turned in both directions and clicks firmly and audibly into place at minute intervals.
