In March 2001, we contacted the German Maritime Search and Rescue Association and started developing a watch that could cope with the harsh conditions of rescue operations. Around a year later, the S.A.R. Rescue-Timer presented and handed over to the German Maritime Search and Rescue Association in February 2002. The S.A.R. Rescue-Timer is the prelude to a series of special Mühle watches that are used by German Maritime Search and Rescue Association or in the German Navy. Each mission watch is developed together with the respective unit and adapted step by step to their requirements.
