The 8541B automatic was IWC answer to the Rolex Steel Oyster models This watch is powered by the excellent IWC calibre 8541B automatic movement which incorporates a hack feature – when the crown is pulled out to adjust the hands, the seconds hand will stop, thereby allowing accurate synchronisation to a time signal. There is also provision for semi-quick date change – whilst the date will change automatically each day at midnight, it can be manually advanced by repeatedly moving the hands between 11.30pm and midnight. Cased in a satin finished, tonneau form case unpolished , the watch reflects design elements that were popular in the late 1960s and 1970s, yet this is a classically styled model with clean lines and an emphasis on visual clarity.
