I am pretty sure, but not Antimagentic as already stated on the cb referring to the movement protection against magnetism by means of an antimagnetic soft iron cover absorbing magnetism. AM refers to the non-magnetic signature of the whole watch. The case...
I would rather say that the TR went first, in 1964 and in 1966, then the AM and the rejected Bronze ( on this last one, we agree ). For me, but it is just a guess as I didn't find any documentation to prove it, the AM came just after the TR. Same case, pr...
if I am not mistaken. How about AM 38 and 103? With military watches, dials were often replaced. First, radium dials lasted only 3 to 5 years. When they switched to only marginally radioactive compounds like tritium, dials were replaced again, and of cour...
A 'T Swiss T' designated dial shouldn't have radium. I think that would have been illegal anyway, as radium was banned for the Swiss watch industry in 1964. If there is strong radiation, it must come from the bezel. The only way to find out, is to take th...
