IWC Portugieser Chrono running slow after complete service

Hello everyone,

After one year, I sent my Chronograph for a complete services as my AD requested:
- Suddenly the watch was running +14s fast a day
- Since I bought it the 6 small second hand was stutering/flickering

After 4 weeks of complete servicing, I finally got back my Portugieser yesterday.
The Small second hand problem is now fixed but my watch is running SLOW -4s a day. I know that IWC specs don't accept a watch to run slow.

Should I wait the watch to break-in after a complete service as a new watch or should I visit my AD again right away ?

I'm really frustrated by this situation, and I would like my Portugieser to work just fine, within the specs...

Thank you for your help and feedbacks,

Simon
