Why it's interesting
IWC's plainest watch, and quietly one of its best: Roman numerals at twelve and six, slim leaf hands, a railway track and a date, on a flat 40 mm case. It's the dress watch for people who'd rather not think about a dress watch.
Watch DNA. Filled tags are editorial; outlined tags come from the specifications.
