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.
