Skal det her IWC ikke en tur til urmageren?

Jeg tror også, at det er nødvendigt med et servicebesøg. IWC´s PC styres udelukkende med kronen. Det medfører, at man ikke kan stille de enkelte elementer hver for sig, og man kan ikke stille kalenderen tilbage.

Her er lidt fra manualen til en ref. 5022
Please note: You must not advance the perpetual calendar beyond the valid date. The complicated movement is permanently mechanically pro- grammed and cannot be turned back without intervening in the movement. If, however, you have adjusted the perpetual calendar beyond the valid date, you have two possible courses of action:
Either you must stop the movement by pulling out the crown to position 2 until the perpetual calendar setting once more corresponds to the valid date. This is appropriate in the event of a small forward misadjustment by only a few days. Or, you must take your watch to your watchmaker, who will be able to adjust the movement to reset the perpetual calendar. This is required in the event of larger misadjustments.
