SINN 900 PILOT S : The Large Pilot Chronograph

Posted on by

Black signifies objectivity and functionality — both of which are inherent in the design of the 900 PILOT S pilot watch by Sinn. But there is a further connection to the colour black: the S in the model name stands for “Schwarz” (black) — signifying the Black Hard Coating of the watch.

There is an overriding SINN priority behind this — the suitability of each watch for everyday use. To achieve this Sinn has additionally hardened the satinised stainless steel case using TEGIMENT Technology. The hardening also provides the base to which the high-grade, black PVD coating can be applied. This combined process results in a highly practical benefit: by applying a coating with a hardness of 2,000 HV (Vickers hardness) to the hardened steel (1,500 HV), prevents the otherwise common problem of cracking paint.

The pilot watch’s other technical features also fulfil the most exacting demands in terms of precision and functionality. The black galvanised dial and the case diameter of 44 mm ensure perfect readability, for instance. Crucial features for professional use include magnetic field protection up to 80,000 A/m, the interior pilot’s bezel and the second 24-hour time zone which can easily be set using the knurled crown at 10 o’clock.
