    Dear Fellow Member of IWC,

    Allow me to introduce myself, Rio Putra. I am a big fan of IWC timepiece
    especially Portuguese. I just recently bought IWC Portuguese 3714-04 with
    calibre 79240 and I believe it is highly modified the famous valjoux 7750.

    I serched for many times in some references of this line that I found that it
    has 31 jewels and it is clearly engraved in the rotor of the movement.
    Surprisingly when I opened my watch then I found the rotor movement engraved
    with the 29 jewels instead of 31. My questions is it true that the IWC calibre
    79240 has 31 jewels or it is some kind of misplaced for it to have 29 jewels.
    For your further reference, I enclosed here the picture.

    I believe the 29 jewels engraved is for Previous lines of iwc, calibre 79230
    (dopplechronograph).

    Thank you. Looking forward to your reply.
