Unless it is a really high end or rare replica watch and / or with a very expensive movement I personally do not think it is worth paying out a similar cost to the watch itself for a service.
Especially so with most 3 hand date only models, which in fact if they do shit their pantaloons you then have the choice, if you can DIY it and it's in VGC swap in a new movement, perhaps an upgrade i.e Miyota 8215 where the A2813 came out, or simply buy a new rep and break up the old one for parts / DIY practice / bin it
I have had around 3 (of approx 100 reps) fail inside 2 years.
1 was a real easy fix, loose rotor, the other 2 got new movements, 2813 swapped for Jap Miyota 8213, Daytona A7750 swapped for an ETA 7750.
