: Thank you, Dan! So much good information here. I think the IWC is a

: have to worry at all about the radioactivity of the Trithium?

: Thanks again for your valuable input.

Hi Patty,
Not at all, the levels of radiation are almost non existent.
But for those working on them “at the source” were more exposed.
Tritium adds so much vintage feel to watches - just look at the old Rolex’, Panera’s, and the IWCs. The list goes on.
I would say that a nice 3713 or 11, complete with the bracelet - is a sure bet and you will cherish in the future.
Good luck Patty!
