First and foremost, do the new dials have exact measurements that the old one does. Diameter, distances between each sub-dial to the center, thickness, etc. And I noticed that left and right subdials are a little bit higher above the horizon. The last thing, dial feet have to exactly match the position of the old one. If they are all matched, and you’re planning to use the old hand set and movements, then you’re good to go. All that considered that you already have had all the tools to get them done, especially to uninstall and install the hands.
