Dear fellow IWC fans
I finally managed to get my hands on and purchase the (unfortunately) now discontinued IWC Portugieser Automatic in White-Gold, IW500106. Upon closer inspection I noticed that though the watch's back one can clearly see plastic parts (highlighted in the enclosed picture).
To say that I was "very surprised" is an underestimation and I was wondering if this can be found on any IW500106 as I have not seen something similar on any other watch model with this price tag.
Your thoughts and advice is highly appreciated!
