Mondaine, the official timekeeper of the Swiss railway system, has debuted the inaugural model in its new Helvetica Watch family at BASELWORLD 2014. Dubbed simply the “NO. 1,” the watch comes in five different case sizes in three different weight classes: Light (26 and 38mm), Regular (33 and 40mm) and Bold (43mm). The style combinations are further multiplied by the various finishes for the steel cases including black, gold and PVD as well as several strap options. The watch face is simplistic and uncluttered and features the infamous typeface of the same name.
