SINN 857 UTC VFR

The pilot watch 857 UTC VFR by SINN has been tested and certified in accordance with DIN 8330 by neutral institutions in an extensive and complex type and unit verification process. It is one of the first pilot watches in the world to be distinguished by precisely defined functional and technical features which enable it to withstand vibrations, shock loads, centrifugal force loads, temperature changes and magnetic fields occurring in flight. This ensures that the pilot watch 857 UTC VFR can act as an all-round replacement for the on board timekeeping instruments available to pilots under visual flight rules (VFR).

These extremely high quality standards are underlined by the installation of a range of SINN technologies. Functional reliability at a temperature range of −45 °C to +80 °C is guaranteed. The surface of the bead-blasted stainless-steel case has been hardened using TEGIMENT Technology to make it especially scratch-resistant. Ar-Dehumidifying Technology ensures greater functional reliability and freedom from fogging.

The 857 UTC VFR is quick and easy to read during the day and at night. The captive pilot’s bezel, which is used for setting time intervals, is attached to the watch and easy to operate even when wearing pilot gloves. The pilot watch 857 UTC VFR also features a second time zone display on 24-hour basis. Dressed in a case made of stainless steel in bead-blasted finish, the watch houses an ETA 2893-2 automatic movement.
