How to move with precision the objects?

I know if I zoom in on the obejct I can do it, but I need to move it without having the zoom

At least turn on ‘View Hidden Geometry’ (sorry, it’s already on) and mayby also face style ‘X-ray

Unhide the edges in your object. They seem to be hidden basic geometry or on a tag that has been turned off.
Right now in your video you don’t even know where you grabbed your object.

You need to grab your object at a well-defined spot, such as a vertex or inference point on an edge, not an arbitrary place somewhere not exactly known. It is usually best to grab a point that you seek to match with some specific point on another object, as that way you can just move it until it snaps to the inference.
