Inspired by the Bauhaus movement of the 1930s that first ushered in the era of modern architecture, this watch is the epitome of minimal design: no text whatsoever, no logos, no numerals, no luminous paint. Completely mechanical, does not take a battery. The BWAF automatic movement winds itself with the movement of your wrist and has a power reserve of 40 hours. The 42 mm wide, 10 mm thick case is protected by a scratch-resistant sapphire crystal.
