Hello
My watch got fully replaced as they could trace back a production error for the batch fabricated early 2024 (my watch was part of that batch). I also understand that the watch inside and out should be fully black so no scratches should appear. I purchased the watch in the official paris boutique during a holiday, but it was replaced through the local and official dealer in antwerp (belgium) afterwards.
Anyway, I cannot stress enough how much I appreciate the iwc and the local official dealer for their top notch customer service and honesty! You can imagine I was quite concerned by the issue after purchasing this special watch. Fortunately, It was a very smooth and transparant process. Therefore I would recommend buying iwc watches throughout official dealerships if possible.
Extremely happy with my topgun cerratanium watch...
Planning to buy the iwc spitfire 326805 next and wouldn't do it, if the response on my topgun cerratanium issue proved to be negative. Looking forward to visiting the local dealer again.
Hope this answers your questions and offers some guidance for others as well
