Do anyone know how to check the correctness of Double moon phase in IWC perpetual calendar?

Hi,

Thanks, Cromagnonman

I ever tried using online information to check the correctness.

However, I still cannot confirm …

Let ‘s see the attached photos, do you think the display of double moon phase is correct or not?

Actually, I don’t know why IWC not includes such information in its website for owner’s reference as IWC is famuous of making Perpetual Calendar …

As with an IWC-Perpetual-Calender, the weekday, date, month, year and moonphase are synchronized, you don’t need any special information about the moonphase. Just put the date right and the moonphase is correct as well. Your pictures of the watch and the moonphases in January 2025 comfirm this.
