Not only Ultra-Thin but Record-Thin! The thinnest IWC ever made, the 1979 Delirium I Tres Mince: innovative construction invented by Maurice Grimm and André Beyner. Solid gold case, hand-made by the case-maker artisans at Favre Perret. One of the rarest and in our opinion also one of the most important IWC ever made -- whether you like quartz or not.
