Sinn 756 Series Duochronograph Collection – 756 UTC, 756 S UTC and 756 DIAPAL

Leading-edge technology from SINN make the duochronographs of the 756 series extraordinarily resistant to pressure and high-altitude conditions. At the same time, the closed case interior with the soft iron sheath provides protection against magnetic fields that far exceeds the DIN requirements.

The features of the 756 chronographs series include Magnetic Field Protection of up to 80,000 A/m, Ar‑Dehumidifying Technology enhances functional reliability and freedom from fogging, TEGIMENT Technology and therefore especially scratch-resistant, functionally reliable from − 45 °C up to + 80 °C and pressure resistance of up to 20 bar.
