I thought I would share my research and thought on 're-lumed' early Radium Trench Watches. We see thousands of these now a days with a thick green material covering the , what was a lovely dial.
I am now quite sure the Radium material originally applied was a grayish white - I can prove this later.
In time that 'radium' does either two things:
1) Turns to a lovely rusty reddish orange - the patina color is magnificent (see first watch LHS below)
2) Crumbles away (like in the hands of the first piece) or is completely removes as can be seen on the second piece from LHS.
Now the disaster happens. Jewelers and Re-Lumers had never seen an original radium applied dial from 1918s. But they saw the adverts that it glowed BRIGHT GREEN. So that is what they applied.
In watch 4, we can see this on the hands a horrible dark green, by picture 4 it seems a bit better but still re-lumed
Here is another example of an original aged Radium dial from 1915
Here is my 1917 Patria - same as first pictures - SURELY re-lumed! Say picture 3?
Now we see a modern disaster, which is becoming the typical normal for Trench Watches:
Of course re-lumers can make it any color, I see white, but its too clean and bright white, I believe the original radium applied was a grayish white.
