The Junghans J805.1 is a hand-wound movement based on the reliable ETA 2801-2. It is featured in the Max Bill Handwound collection, offering a slightly longer power reserve than the automatic variants at 42 hours. The thinner profile compared to the automatic J800.1 makes it ideal for dressier, slimmer watch cases.
