Victorinox Swiss Army I.N.O.X. Mechanical 241837. At first sight, nothing distinguishes the quartz model from its mechanical version, with identical style, proportions and features, three hands and date. However a transparent back case show the mechanism behind it. The guilloche dial, in the style of the Swiss officers Knife is what makes the design stand out. I.N.O.X. signature bezel has been coated to make it even more resistant to wear and tear keeping the shine intact for longer.
