IWC Aquatimer Perpetual Calendar

Limited to just 50 watches and available exclusively in IWC boutiques, the Aquatimer Perpetual Calendar Digital Date-Month is the flagship of the new 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 date and month discs have perforated covers inspired by the filter systems that are omnipresent on submarines. 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. The Aquatimer Perpetual Calendar Digital Date-Month is a genuinely big watch: with an impressive diameter of 49 millimetres, it is the second-largest wristwatch in IWC’s history after the Big Pilot’s Watch of 1940. The IWC SafeDive system ensures that the bezel can only be turned anticlockwise, and that zero hour – a dive time requiring no decompression stops – is not inadvertently exceeded. 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.
