Thats very interesting Marcello................
Do you know when these services dials were introduced, are they from the 60's or later and just done in the style of the earlier 50's/60's dials? Are the hands still original to the watches you have seen with these service dials? Are these dials Radium?
If these service dials are from the 60's is there any pattern you may have noticed regarding the watches the service replacement underline dials are in. Are they certain years or within a serial number range or just random replacement of dials during a service?
The reason why I ask is whether they could have been used to replace other dials that did not conform with the US standards for radioactive materials eg low Radium limit introduced in 58 or the use of other luminous material such as Strontium following the 1959 USA GMT scare.
I appreciate I'm asking a lot, but just trying to understand more about such an interesting underline dial that has always been subject of hot debate as to the significance.
All the very best
kind regards
