Agree, Rolex pricing for SS seem rather sane while also showcasing real-world movement improvements in not just accuracy, but in longevity between service intervals. Rolex also decorates their movements... even in places never seen by the customer.
For other 'Swiss' mechanical timepiece manufacturers, the story might be starkly different. Seems to me even small efforts of movement decoration are being ignored by some Big Box manufacturers, or they only decorate a tiny bit that might be seen in a display back. Kinda misleading imho, definitely a 'cheapening' of the product imho as compared to Rolex.
And plate sandblasting is not a movement 'finish' that takes any real effort imho. At least the industry could... well, you know, don't make it sound like it is something so very special and expensive to do. Is it only me who sees this happening ???
NOTE: Technically, virtually anything could be called 'decoration', tho i hope true fans of horology understand there's hand decoration of various techniques (some being quite challenging / much-talent is needed), machine decoration (thank a computer programmer).... and sandblasting (normal procedure) a 'finish' after machining.
