The external rotating bezel, whose arrowhead index marks the beginning of the dive, likewise gives the Aquatimer Chronograph in stainless steel a striking new face. To ensure that they stand out clearly, the first quarter of the bezel and the minute hand are finished in luminescent marine colours: coral red combined with a dark blue dial or signal yellow with black. Yellow is only filtered out in very deep water and is thus visible for an unusually long time. The diver’s watch, which is water-resistant to 12 bar, has increased slightly in girth and, thanks to the Super-LumiNova* coating, is considerably more legible. The much lighter subdials for the minute and hour counters also make it easier to read stopped times under water. Both versions are available with a stainless-steel bracelet or a blue or black rubber strap. * IWC Schaffhausen is not the legal owner of the Super-LumiNova trademark.
