The 756 series pilot’s 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 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 minus 45°C up to plus 80°C and pressure resistance of up to 20 bar.
The special in this instrument chronograph is the DIAPAL Technology. First developed by SINN in 2001, it is now in successful practical use. The starting point for our considerations back then was the critical feature of every mechanical watch: the aging of the oil, particularly around the Swiss anchor escapement, and the accompanying adverse effects on the accuracy of the movement. Theoretically, it was only a small step from the analysis to the solution: where there’s no oil, there’s no aging. However, this concise expression required numerous tests in practice. The technology is documented by the DIAPAL logo on the charcoal grey galvanized dial.
