Yup, and on a watch-by-watch basis. I have 21 watches right now in my box: 5 quartz, 16 hand wound/automatic. Broken down further:
01x >$1000 Quartz
04x <$100 Quartz
11x <$700 Mechanical
05x >$1000 Mechanical
Of the entirety of the Quartz watches, only the $1000 Quart watch may ever get serviced, because it is a rather unique calibre/movement - though by the time it finally dies and NEEDS to be serviced, parts may no longer be available.
Only 1 of the <$700 mechanicals has enough meaning to me to demand a servicing, but the labor is worth more than the watch, and the value of the watch is purely sentimental.
This leaves the 5 >$1000 Mechanicals. Of that batch, ONLY one has the monetary value and the sentimental value in my mind to be serviced (My Speedmaster), and I actually DID pay for a service on it last year after nearly 10 years of ownership. Amoratized to $75/year of ownership, that wasn't too bad. I might be convinced to service my Carl F. Bucherer as well, but the other watches in this group are gonna get run till they stop and may be retired at that time. Likewise, I may inherit 3 watches from my dad - THOSE may actually get servicing.
