thanks for all comments, I realized it misses the inner cushion. Some assurance that it is marked 'Made in China'nowadays. I'm in contact with the seller now to discuss the origin of this case.
UPDATE: I met with te seller today, and he took an older box with him to compare (one that says IWC Schaffhausen - Switzerland on top). It is completely comparable, but the newer boxer are indeed produced in China (it therefor explicitly says "box made in China". The interior of the older boxes are off-white, this newer version is more white. He convinced me, thanks to your comments as well.
