Case opening on a invicta and movement question

[Izzy1997]

Hey first time taking apart a watch and I have taken off the back to get to the movement but not too sure how to take off case to get too dial and just wanted to know what type of movement this is cheers

This is invicta model 13086

The movement appears to be an Epson YM91A.

To remove the movement from the case, you'll need to first remove the stem.
