These watches are from a guy, Andrew Pierce, who founded the company thebestwatchesonearth LLC two months ago in Wyoming USA. He seems to have registered thousands of companies over the years in Wyoming.
As to the watch itself, a tourbillon watch (tourbillon means "cage" and is a way to keep the balance wheel/escapement--the two things that create a steady tick--suspended in a rotating cage so that gravity doesn't unduly effect them, since it is constantly rotating) usually costs upward 15K or more, but a guy named Oliver Mory managed to produce a tourbillon for 4K that he markets and sells to small independent watch makers. The movement is called BCP T02 caliber, which is found in his other watches (<--all this info comes from my friend Jessica, who knows watches!). What ostensibly makes this watch cost a lot is the gold and diamonds, not the tourbillon, but your name must be "Emir" if you're going to spend 100K on this watch and think you're getting a good deal. This Andrew Pierce guy probably just realized that he could talk to Oliver Mory's company, pre-order some watch movements/cases, bling them out, and then grift the Trumper's who have already been grifted by Trump. Andrew Pierce's company has no affiliation with Trump or his campaign.
