Reduced to a minimum, the design focuses on the essentials – the hour and minute display. The resulting clarity, skilfully combined with the polished, rhodium-plated appliqués meticulously attached by hand, conveys a harmonious overall appearance.

The case of this two-handed watch is made of 935 Argentium silver alloy. The advantage of this over traditional precious metal is that rather than tarnishing and blackening like normal silver, Argentium forms a protective germanium oxide surface layer. This layer considerably slows down the tarnishing process. Instead, a golden hue develops, which can be removed with an Argentium care cloth.
