Sinn 856/857

Sinn 856 and Sinn 857 – instrument watches engineered for extreme environments

The Sinn 856 and Sinn 857 represent some of the most technically advanced instrument watches in the Sinn Spezialuhren collection. Developed for professionals who demand exceptional reliability and durability, both series have also become favourites among watch enthusiasts worldwide.

Both collections follow the same philosophy of uncompromising functionality. The Sinn 856 is a clean three-hand instrument watch, while the Sinn 857 builds on the same platform with a fully automatic chronograph.

Designed for demanding conditions

The Sinn 856 and 857 were developed to perform in environments where conventional mechanical watches may be affected by magnetism, moisture and rapid temperature changes. Their purpose-driven construction makes them true tool watches built for everyday reliability.

High-contrast dials, bold hands and excellent legibility ensure the time can be read quickly under virtually any lighting conditions.

Anti-magnetic protection

One of the defining features of both collections is their anti-magnetic protection. The case shields the movement from strong magnetic fields, helping maintain accuracy in technically demanding environments.

This makes the watches particularly attractive for professionals working around electronic equipment, industrial machinery and other sources of magnetism.

TEGIMENT Technology

Many versions feature Sinn's proprietary TEGIMENT Technology, which significantly hardens the stainless-steel surface. This greatly improves scratch resistance while preserving the watch's appearance during everyday use.

Ar-Dehumidifying Technology

Sinn's Ar-Dehumidifying Technology reduces moisture inside the case and helps prevent condensation during sudden temperature changes. It also creates a more stable environment for the movement, supporting long-term reliability.

Sinn 856 or Sinn 857?
