FWIW, I just got a 2500c back from omega service. They replaced all the escapement parts. So I have the originals in a baggie. Smallest escapement parts I've maybe ever seen.
My watchmaker runs an AD, and he says it's not worth the effort to service coaxial on site. They do all non-ciaxials in house for less than the omega charge if desired by the customer, but for the $680 omega charges for a coax movement, he just sends them all out. Not profitable use of their time to do it themselves, he claims.
