The platinum edition was limited to 500 sets globally, though individual pieces were also sold separately. Collectors value this reference for its use of in-house manufacture movements, such as the caliber 98245 in the Portuguese and the caliber 80111 in the Ingenieur, housed in 950 platinum cases with silver-plated dials and sapphire casebacks. This set represents a transition toward IWC’s modern manufacture era while maintaining historical dimensions. On the secondary market, individual platinum pieces typically trade between $15,000 and $25,000, while complete six-watch sets in the original presentation trunk are rare, often valued in the low-six-figures.
