The 900 DIAPAL brings together a number of different SINN technologies which, when combined, yield maximum reliability in terms of time measurement and functionality. Worthy of particular mention here is DIAPAL Technology for a lubrication-free anchor escapement. This is documented by the DIAPAL lettering on the electroplated charcoal grey dial. As a result of this extraordinary technology we offer a five year warranty on the 900 DIAPAL. The large pilot chronograph also features Ar-Dehumidifying Technology for increased functional reliability and freedom from fogging. The sanitised stainless steel case has been hardened with TEGIMENT Technology making it especially scratch resistant.
