IWC Portofino 8 day Issues with time-Setting

Hello All,

I have a 3 month old Portofino 8 day reserve (mechanical, not automatic). It is under warranty but, for now, I have no place to take it to here in Michigan so I wanted to ask @Archer or any knowledgeable member about a little issue.

The watch keeps perfect time. There is no issue there. No issue with winding. Date wheel and setting is smooth and works perfect but, when setting the time, and ONLY when setting the time the crown increases in resistance as you move go along setting the time.

This was not the case to start with. If I have not used the watch in a while when I set the time I always go once around the 12 O'clock time to make sure I'm not setting on the AM and then at noon the date will change or setting in the evening to find the date does not change at midnight. So about a week ago I started to set it and as I moved through the 24 hour cycle it started to get harder and harder in resistance up to the point that it really feels like the crown is going to get locked. The interesting thing is at that point if you set it to start then the watch continues to perform perfectly, so the resistance only affects the setting mechanism.

I'm not looking to resolve it on my end, I'll send it to IWC. I am just curious as tom what may be going on.

Thank you for any insight.

it doesn’t go back to normal which makes me think maybe one of those seals
May have just slipped out of place ( if that’s a thing)

Thank you for the feedback as it makes me think that the movement would be unaffected. I say this fully aware that neither you nor I can make that call without opening it, and that you are not implying that either, but I’m just being hopeful.
