Complications of the kind you mention aren't what Rolex is about these days.Is it? Have Rolex ever produced a tourbillon or Grande sonnerie? Brands like Seiko have produced both in-house. Chinese brands like Sea-Gull have produced a tourbillon movement. Is it because Rolex is incapable of haute horology? I think a lot of Rolex owners are interested in owning something that says Rolex on the dial. Rather than buying a high end brand. These are just some thoughts feel free to discuss.
Franck Muller built a perpetual calendar using a Rolex DateJust in 1989. This is probably the closest we've got to seeing a Rolex equipped with such complications in the modern era (and that too was a one-off personal project built for a friend).
Rolex in 2020 focuses on high-quality construction of relatively basic designs. Even once functional components - such as the fluted bezel - are now just ornamental. It's high-quality work but typically doesn't break new ground on the complications front. The one exception might be the Sky Dweller.
For build quality alone, Rolex watches are worth their salt in the $5,000-$15,000 MRSP range. That's to say, I'd pay within this range for Rolex watches, and I have. It also means that I would never, ever pay any more for one. Above $15,000 and you should be expecting watches that deliver creative fireworks, not just more precious metals or gemstones.
