Silicon Hairspring/Escapemenet & Watch Servicing

[RickTock]

Some time ago I read that watches with a silicon hairspring or other escapement components had to go back to the manufacturer for servicing. Is this true?

In terms of skills, tools and lubricants, what would be required over and above those possessed by a traditional watchmaker to service a watch with a silicon hairspring or other escapement components?

Several problems would occur. Special lubrication methods may be used special tools.Timing for instance it really should have probably a very very nice timing machine that gets calibrated on a regular basis if you really want to offer super precise timing.

But there is the biggest problem of all liability of breaking something and zero availability of ever getting spare parts.
