They are both extremely well-known luxury watch manufacturers. The fact that you haven’t heard of them has nothing to do with them, it just means you’re not into luxury watches.
Indeed. In case I didn't explicitly state it, I was expressing more of a fascination that there are these companies that seem to make high priced luxury items (so they have to be low volume, and likely handmade) but are still large enough in scale to afford these massive fancy buildings, as opposed to be boutique watchmakers, which is how I would intuitively think of this class of craftsmanship.
