The bold contrast between the dial colour and the subsidiary dials makes this model instantly recognisable and as such it has long been lauded as a design icon. The current example is a particularly rare example, in the same family since the 1970s, a 6239 with the inner case back numbered 6242. Another example of this reference combination with a 2.0 million serial number was offered for auction in 2017.
