Limited to just 50 watches and available exclusively in IWC boutiques, the Aquatimer Perpetual Calendar Digital Date-Month is the flagship of the new IWC Aquatimer collection. The distinctly technical design of the dial is characterized by the extra-large numerals of the perpetual calendar, which is mechanically programmed until 2100.
The designers took their inspiration for this particular element from the filter systems that are omnipresent on submarine vehicles. This provides a view of the complex switching mechanism at work: a fascinating spectacle, particularly at the end of the month, when all four date discs move simultaneously. The four-year leap year cycle is also shown digitally.
With an impressive diameter of 49 millimetres, Aquatimer Perpetual Calendar Digital Date-Month is the second-largest wristwatch in IWC’s history after the Big Pilot’s Watch of 1940. The external rotating bezel is made of 18-carat red gold, as is the protective cover on the left side of the case for the advanced sliding clutch system, which transmits the rotation of the external bezel to the internal rotating bezel.
The casing ring, push-buttons and crown are made of rubber-coated titanium. While the attractive black rubber strap with its black alligator leather inlay guarantees maximum comfort in wear and a long service life, the unusual combination of red gold, rubber and leather gives the watch a look that is both classy and sporty at once.
The see-through sapphire-glass back provides a view of the IWC-manufactured 89801 movement, which comprises 474 individual parts, and its highly efficient double-pawl winding mechanism. The rotor has a distinctly functional look and feel and alludes to the reliability of research submarines.
The Super-LumiNova® coating on the hands and indices glows particularly brightly in the dark in two differentcolours: green for displays relevant to dive time, blue for the hour display. The imposing Aquatimer Perpetual Calendar Digital Date-Month is water-resistant to 10 bar.
