К вопросу используемого IWC масла:
Цитата:
IWC uses a variety of oils in diferent parts of different movements. For the Cal. 37582, for example and as shown here, IWC uses primarily JISMAA blue but also uses Moebius in a few places. On the other hand, I've seen other IWC movements with more than four oils, including JISMAA but also various different Moebius oils, including 9010, 9415, and D5.
Every oil has its unique properties and getting just the right amount of the right oil is very complicated in high-end movement assembly. This is especially true in new movements where some trial is necessary. It is more of an art in my opinion.
