I recently had a Big Date on the work bench and the gear ratio is very tricky. The date should run from 01 to 31 and start again from 01.
Someone probably already worked on your watch and didn't know what he was doing or it happened in China.... To adjust it you need to strip it down and adjust the interconnection of the gears and date wheels.
Looking good but the cut outs are missing the point...
You want your upper body comming closer to the bench while you arms have a resting point. Therefore al the watch makers benches I have seen have an opposite cut out: inward curve.
An example:
The hand is not glued. It is the tube that is pressure fitted into the hand that is glued. The tube than needs to be pinched.... Oh man no one will ever understand what I just wrote
Either a front loader or a gen like construction. The latter meaning that the screws need to be screwed in (not out) and than the movement ring needs to be turned until the screws fall into a gap making it possible to remove the movement.
Just turn the crown anti clockwise until the date flips. Then you know it is 12 o'clock. Position hour and minute hand right in line with each other exactly at 12 (date switch point).
A2836s is are new movements. The Swiss ETAs that come in our reps are mostly NOS or old salvished movements. Both need service in principle.... Buy a Swiss sealed ETA movement so you know it is fresh or buy an Asian clone and have it serviced would be my advice.
