Servicing Affordable and Luxury Watches?

Hey there,

I was recently talking to Roland Schwertner (Nomos) and he told me Watch Service needs to be done at least every 10 years. But a watch Service on a Nomos can cost about 300€ and for other luxury brands even a lot more. So how do some of you with collections of 20 or even 100 watches handle this. 

Do you not service your watch at all or do you spend a fortune every ten years to get them serviced and what about watches with for example an NH35 movement. I can imagine at a price like that the watch becomes disposable!? 

Please let me know what your take on this is.
