JLC Service Q’s

[829maxx]

Hey All,
I’m looking at potentially purchasing a pre-owned Master Control Reserve de Marche (140.8.93) and thinking I may get it serviced sooner rather than later even though it’s running quite well per a timegrapher.

My question is whether a JLC should always go back to the manufacturer for service or if there are reputable, trusted, and more “affordable” 3rd party servicers for a JLC. Also, is this model with its basics complications too complex for any reputable local watchmakers to service assuming it doesn’t need JLC parts when serviced?

Thanks in advance! Pic for reference from the web.
