Grossmann movement architecture is deceptively simple, but I can assure the actual finishing is miles better than Lange.
The jewel cups are bigger and taller and dramatically dished, the screws are violet instead of blued, the polishing is far slicker everywhere, literally all numbers and text is engraved by hand, every single gear tooth is polished to perfection, look at that worm gear for the balance adjuster needle, etc.

It's almost a big of a step up from a Lange movement as Lange is from an Omega movement.
