I’m really, really curious.
I am the proud owner of a JLC RDM that brings me more and more joy each day. One of the aspects that impress me is the fact it has a 273 parts and 41 jewels (that should reflect a complex movement) movement that is so thin. But how can it be so “complex” while the new Master Eight Days Perpetual SQ – with a complication supposedly more intricate than a reserve de marche function – has fewer (260) parts?
Looking forward to reading the experts' comments

A few things...
Your RDM is an automatic, the Perpetual is a manual wind - big difference. Also, a power reserve indicator can, depending on the design, actually involve quite a lot of parts, and be quite complicated (compared to what you might expect). Not just a couple...
