Finally got my JF Yachmaster and tore down the movement. It's definitely a Yuki 3135. Here are some highlights:

- Different (better?) datewheel print
- Different yoke for cam (don't know why)
- Engraved bridges (3135 too small though)
- definitely NOT *fully serviced

The last bullet - it appears that the winding bridge and auto assembly have been nicely cleaned and oiled which makes sense if they removed them to do the engraving. Performance out of the box was standard low-amp Yuki. The finish was nice and shiny on the engraved parts but still dull on the rest of the movement. Pics below. JF is on the left.



I didn't take pics of everything because they're identical otherwise.

 
No, different movements.
JF = Yuki
Noob is different.
