Did you see the caseback and the hallmarks on it and the case? The movement looks like an L48, not a 151, and definitely not a 49. -
I have both but prefer the digi. I asume i need to test the coil for ohms somehow or if theres any voltage running thru -

You were always going to be up against this project, but you had the guts to go for it. Determination will see you through and you certainly have that. Good luck with the rest of the work 👍 -

Ran into some BIG TROUBLE After laser welding both the sides and all 4 lugs, I measured the crystal and retainer ring area so that I have rough dimensions to cut to post welding. To my surprise, the dimensions from 3-9 are 0.6mm smaller then when measured from 12-6. The same dimension difference was observed when measuring other points. This means that now the case is friggin oval shaped. Fortunately there is no warping or deformation on the other axis. I was careful enough to not hold the case tight, my best guess is that the heat stress and material anomaly/deterioration has led to this. I am still committed to this project but a few more steps got added and it has now become an all or nothing deal, will be posting updates
