They are very similar to Mark XVIII, but there is no "MARK XVIII" symbol on
the dial and the officail name are "PILOT'S WATCH AUTOMATIC SPITFIRE/TOP GUN",
so do they still belong to Mark XVIII Edition?
Second question: In around 2015, the calibre families 69000 (chronograph) and
42000 (automatic) are announced to launch for the the entry level IWC's
watches. Now that we do have the Cal.69000 (chronograph) and Cal.32000
(automatic), what about the Cal.42000? Is Cal.32000=Cal.42000?
