Muehle Glashuette Watch S.A.R. Rescue-Timer M1-41-03-KB. When developing our watches we don't rely solely on our own know how, but also allow ourselves to be influenced by others as well. Indeed, we even welcome it. The function and design of the S.A.R. Rescue Timer, for example, were to a large extent determined by the captains in the German Maritime Search and Rescue Service. These captains control the rescue cruisers answering the call of duty to save sailors in distress in all kinds of weather.
