Newly developed moving horns with curved lugs ensure that the black alligator leather strap by Santoni fits wrists perfectly. The stainless-steel chronograph shows elapsed minutes and hours on a subdial, so that the stopped times can be read off as if on an analogue watch. As usual, the timepiece has a central chronograph hand to show seconds.
The in-house 89361 chronograph calibre has a 68-hour power reserve and draws its energy via the automatic IWC double-pawl winding system, which has four pawls to transmit energy to the pawl wheel. The watch is water-resistant to 3 bar and has a flyback function: pressing the push-button stops, resets and restarts the chronograph instantaneously.
