Looking for Thoughts on Next Purchase - Cartier vs. IWC

[Cuts33]

I have been going back and forth for awhile on my next purchase and "just get both" unfortunately is not an option.

I have narrowed it down to 2 pretty different watches.

The Calibre De Cartier with white dial on a strap and the new IWC Pilot 3777 on a strap.

For the Cartier, there is something about the white dial that I love but cannot put my finger on it. The detailing is truly remarkable and I am a big proponent of in-house movements. I know the history of Cartier and watches is a bit murky but they seem to be moving in the right direction.

For the IWC, I have always been a sucker for pilot watches and while not a 3717, I still see this as a "classic" pilot watch. The only thing that really gives me some hesitation is the price tag for a Valjoux movement given that IWC no longer puts the pieces together in-house but relies on ETA to build to their specs. Something about this just bothers me for some reason.

I realize these are completely different options but any opinions or thoughts are very much welcome. Also, just to add, the Cartier would be the only white/silver dial watch in my collection. Both will be the only "strap" watches in my collection as the rest are on bracelets. I do already have more of a "dress" watch that is a black dial. I would like to be able to wear my new purchase with a suit to work (typically 3-4 times per week) but as I said, do have another option if the situation requires it.

Thank you in advance for any input.
