Is there a forum for Cartier watches similar to omegaforums.net?

Cartier has a long history as a watch manufacturer, including of the iconic tank which has been made continuously in basically its current form for more than 100 years. I'm not really a Cartier fan, and they went through a very ugly period where they capitalized on their name to sell crappy watches, but they are a legit watch manufacturer, IMO.

I don't know of a specific forum for Cartier, but the OP can certainly post in one of the relevant sub-fora on OF, and there may be other Cartier enthusiasts.

I think it's a bit more nuanced than that. If you are thinking only of the movement, I think that Cartier historically outsourced movements until fairly recently. Of course, many other manufacturers (including Rolex) did the same. But a watch is not only a movement.

TBH, I am really not the right person to defend Cartier as a manufacturer, since I have never owned one or even gone very deep in research. I understand that because they are primarily considered a jeweler, they might not appear to be a serious watchmaker at first glance. But I don't think that's really the case. Through much of the 20th century, they made high quality watches with unique and distinctive designs that remain highly collectible. They went through a low point (IMO), where they made a cheap and popular line of watches that were little better than fashion watches, which hurt their reputation. More recently, Cartier has re-emerged as a serious manufacturer with in-house movements.

Perhaps the OP can provide correct any errors in the above, and provide more context better than I can.
