Thank you, Alan. Looking at the best-preserved specimens (more)
I have sometimes wondered whether the luminous indices of these watches might have been individually molded units, glued into the wells cut in the dials. The uniformity and symmetry of the doming suggests this, but has been obscured in so many specimens by clumsy re-lumination in the service.
This might be a useful point for collectors in future, as quite a few military watches have recently had their original dials replaced with NOS factory substitutes: IWC, JLC, Omega. When JLC renovated my Mk XI, they opted for the flat fill method (using an oddly "period"-looking beige material, rather rough, that was scarcely luminous when new). No experience of IWC but I'd love to know how they handle this.
If the flat fill is the mark of a NOS dial with luminous applied at the factory in the late 20th or early 21st century, it will provide a way for collectors to distinguish these dials from the originals.
