I have a brand new ETA 955.412 movement replacing another with stem damage. With the following steps:
Place minute/hour wheel.
Place front plate and secure.
Place hands (pressed on easily).
Inserted new battery.
Ensured crown is pushed fully home.
Trouble is, it doesn't function at all. My first thought is I messed it up somehow! Whilst I'm no watchmaker, my day job is engineer so I'd like to figure it out (if the movement was not bust from purchase).
What I've checked is:
Changing time with crown works perfectly.
Date changing functions perfectly.
New battery (voltage 1.58V) measured at chip.
Coil measures 1.5k ohm.
Current draw of around ~2uA.
I'd be grateful for any advice!
