also be careful if you polish your watches, some cloths (such as cape cod) will make any brushed areas polished. Not sure if it pertains to yours.
The 190 is a beautiful design with a great movement. For me its size and shiny case would be the reasons I could not wear it to work. At 44-45mm its just too big to not be noticed, by the boss or our clients. Its definitely something I could wear on weekends. For work I generally stay around 40mm. I regularly wear my AP RO Jumbo 39mm, 38mm Cartier Pasha Chronograph, Cartier Tank XL, Vacheron dress watches, Rolex Submariner, Explorer 2 (old 40mm size), and occasionally a Rolex Daytona.
Once watches get to be 42mm or larger they don't easily stay under shirt cuffs and they draw more attention due to size. While our clients want us to do well, if a watch or car seems too flashy and expensive...they start to resent it, wonder if we charge too much, and if they are footing the bills for too many of our toys. Its just easier to fly under the radar with more average sized watches (particularly ones with brushed surfaces).
I know some of the guys around here think a PAM can be worn with a suit, I tend to think only some of the smaller sized models and even then its a stretch. When I see a guy wearing a 44+ mm watch with a suit, particularly a PAM, IWC BP, or Hublot Big Bang, I tend to think the guy doesn't have a real dress watch and is having to make due with a sports watch. Sure some guys like to see how far they can push the style envelope, but I've rarely seen someone wearing a very large sports watch with a suit and thought they really had something that worked well together.
As for polishing a watch, I just leave mine alone. I've had a few friends that tried polishing their watches and they made a mess out of the finish. Just let it get a natural patina. If it ever needs refinishing let a factory authorized service center do it when its in for service. Even then, I'd probably opt not to get the watch polished except maybe once or twice over many years, because you often lose fine beveled edges and factory lines start to soften after a few polishings. Again great watch...enjoy it!
Dino did you ever share pix of your AP RO?
I know I've said its not my fav watch, but I do love me that bracelet!
