The 857 pilot watch is designed as a functional instrument watch in the tradition of cockpit navigation chronograph clocks and is equipped with a pilot's bezel. This allows set time intervals to be measured, monitored and controlled - an essential criterion, especially in aviation, which is why Sinn designed this important function to be as effective as possible.

Perfect readability in highest quality

The stainless steel pilot's bezel with minute ratcheting can be rotated on both sides and is permanently connected to the case by a mechanism developed by Sinn. The base of the bezel, like the watch case, is tempered with TEGIMENT Technology. Fo maximum readability, the inscription is in silver on an embedded, black anodised aluminium ring, with a luminous triangle as the main mark at twelve.
