I’m having a hard time seeing exactly what’s going on, even when I zoom in as much as possible, but it kind of looks like the hairspring has gotten itself tangled up. How does the spring look when you place the balance cock on your balance tack? Tangled? -

Agreed. There are many different automatic winding mechanisms, each with their own quirks wrt. lubrication. Access to the specific service instructions is the ideal. Otherwise, ask here for advice on the movement you are working on. -

I put the original broken glass (whats left of it) behind the acrylic. This is how it originally looked like. A cheap clock but I like it. Very noisy when the alarm comes wake up guaranteed! 🙂 -
If at all possible, find a service guide for the automatic movements your work on, because the lubrication procedures may have different requirements or rely on oils you would not use in a manual wind train (in addition to the braking grease you mentioned). Some autos like older Seikos do not have a manual wind option, so the procedure of letting down the mainspring without being able to use the crown may require a screwdriver in the ratchet wheel screw and great care. Do you have an auto movement you were planning to start with?
