Time for service?

Hi All,
New to the forum, looking for some info on servicing. I recently purchased a Tag Heuer 2000 Super Professional automatic chronograph. The watch has a LWO 283 movement which is a ETA2892 coupled to a Dubois Depraz chronograph movement. The watch looks to be in great shape given its age, but is running about 15 seconds slow a day. The chronograph works really well, no other issues but the slow time. My question is should I get it serviced now, or wait until it starts to loose more time? Also, does anyone know a good watch maker in the southwest that works on Tag Heuers? I am reluctant to sent it back to Tag for the service, and living in Santa Fe, NM there are few options as far as watch makers.
Any help/guidance would be much appreciated!

Yes, a service is probably overdue, but it's possibly not urgent if 15 secs doesn't bother you. It probably will get gradually worse over time. I would think most independent watchmakers would be able to service it.

Wow, nice piece!

Thanks!
