Digging through some of my movements today this one caught my eye. Anyone recognize this movement? The dial has same private name as the movement.

Looks Swiss for sure, pretty elabaorate regulator setup.Looks like a higher grade movement, whoever made it.

Rob,
I've seen this with the Gruen name on it. It may be an J. Assman made movement, though.

I thought it kinda favored a Lange but I really have no idea.

Kevin you maybe right I just looked up gruen and see it at the top of the page. Thanks

Rob does it run. I needing a regulator part.

Yes it ticks away when I hold pressure with a bench key so I imagine it needs a COA
