This case is worthy of a decent movement. You would have to hold this case in your hand to grasp just how enormous it truly is. You can see that it doesn’t even fit correctly on my stand. This case can only work for lever set movements. Please use the photos as a big part of the description and please contact me with any questions. Case: Open Face, both covers screw on/off. Maker: Illinois W. C. Co. Outside D : 63 mm. Inside D : 44.87 mm.
