Miyota Movement found in very old replica!

[AeroxAerox]

Hi,

i get a very very old replica. Its a Daydate in gold. The movement works but only for a few seconds.
Did anybody know what a miyota it is? I'm a newbie on this area.
Is it possible to make service for this one on a watchmaker?
And can i mod this mov in another rep Rolex?

Cheers
