Movement identification 4131?

[Serdatti]

Good Morning,

i wanted to know if someone Can Tell me Which Type of Movement this is?
It is Build in a OlderDaytona 116xxx (Factory Not known)

It Looks Like a 4131 But Compared to a CF 4131 it Looks „Cheaper“

Got a dial side picture? I'm guessing it's a 2813 burried under the poorly done deco plates.

That’s an SH4131 v2. Easy to ID from outward facing regulator and beat adjustor with counter clockwise hairspring coil.

And beside of the Bad plating, is it comparable to current clean sh4131?

Probably. The photo is low quality, probably taken in low light so there are artifacts. It’s hard to see if the rotor hub has three real screws or if that’s a decoration plate. Also it looks like the balance doesn’t have a paraflex shock setting—it appears to have a different style shock setting. So this might be a lower spec version of the sh4131.
