Please post a pic of Cal3135 movement with its engraved serial number

[RolexDivers]

Hi folks,
I have heard that each Rolex movement of each watch has the watch's serial# engraved on the movement.

Can someone please post a pic of the 3135 movement showing the serial# and its location?

Please hide the serial# ---- I just want to know where it starts from, its location on the movement and how much of the serial # is visible and how easy is it to view.

If you do not have the Cal3135, then any other ROLEX movement will do... I'm sure the location is generally the same.

Thank you.
