Choose your watchband

The unusual and industrial-style ARMURE model features highly technical lines representing a complete break with traditional watchmaking conventions. 

In this instance, function creates design, since aesthetic and technical elements are inseparably entwined. Composed of 36 elements – compared with only ten or so for traditional models – the case houses unprecedented innovations stemming from high-precision workmanship. A degree of complexity that for the first time makes it possible to apply the principle of mechanical sealing technology to a watch.

Three years of research were required to develop the nO-Ring® technology, by which two clamp braces – the caseband and bezel – tense the various case elements together via specially in-house-made satellite compression springs. Dedicated surface treatments ensure unfailing, gasket-free water resistance.
