Tritium first, Radium later...?
Here is what the nice guy at Blancpain vintage department said in answer to this question:
"The no-rad sign which appears on your watch should be an indicator of the use of Tritium instead of Radium. Our attached analysis reports clearly show, however, that Radium has been used on some of the luminous parts of your watch. It is my opinion that, as the intensity of Tritium fades over time, it is possible that a watchmaker has previously replaced the Tritium with Radium."

Do I let Blancpain service my 1960s Fifty Fathoms?
Hi everyone Although I've owned a Blancpain for a while, I don't really know much about them. If any of you have a moment, I'm interested in reading your advice about who should service my watch, and what I should ask them to do: I inherited a 1960s civil...
1960s FF information leaflet
Here's the info leaflet that came with the watch. I notice the picture of the watch on the leaflet does not match the actual watch (absence of "no radiations" marking, etc). Sean This message has been edited by Sean100 on 2015-11-28 05:54:05 ...
If it were me, I'd get my watch back
and have a competent local watch repairman inspect, clean and adjust it. Otherwise you'll end up with a newish looking watch with new dial, hands and no patina. That's my opinion which is not necessarily what you might want to do. Cazalea
A bit confused...
If the watch has a "no radiations" dial as described, how could it contain any Radium?
Yes, good question, I had not thought of that Dave
Maybe radium was not considered to be as heavily radioactive as the substances used in the Milspec watches (e.g. Promethium 147)? I wonder how a dive watch in the 1960s could be luminous without using some kind of radioactive element on its dial...?

Or... They reloaded your tritium indexes. I highly doubt they replaced tritium with radium.
While it would be less curious and more logic to have radium replaced with tritium. Best, Nicolas
Blancpain,
I am not an expert with Blancpain but based on my experience with Rolex and Patek Philippe watches I would not restore the dial or hands of this watch . Never,ever. I am not sure about the health issues with radium used on the watches in 1960s but I am su...
Yes it seemed an odd suggestion from Blancpain...
... to mess about with the dial, Tom. The nice people in the store mentioned that there aren't many of these "no rads" 1960s Blancpains around, and that the company had to appeal to collectors to get some together for an international show they held a whi...
