757 DIAPAL

The 757 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 include Magnetic Field Protection of up to 80,000 A/m, Ar-Dehumidifying Technology and pressure resistance of up to 20 bar. The pilot's bezel make these watches perfect, all-purpose instruments.


The stainless steel pilot's bezel with minute ratcheting can be rotated on both sides and features a special mechanical system developed by Sinn to protect against loss. Like the case material, the base of the bezel is tempered with TEGIMENT Technology. The labelling is silver on an inset, black anodised aluminium ring to ensure optimal scale readability. A luminous triangle serves as the 0 / 60 minute mark. The rotating pilot’s bezel can be turned in both directions and clicks firmly and audibly into place at minute intervals.


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 anthracite dial.
