It's unbelievably hard trying to find one of these... does anyone know where one can find one?

 

Omega sells them. the new ones have SL instead of tritium, but neither are marked with the T's normally found on vintage dials.

part number: 064WJ1868501

If you want a proper vintage one, well, good luck! One sold here a few months ago for a reasonable price.

 

Actually, the original 376.0822 did NOT have T's on the dial. See my photo above.

 

Yes, correct. neither the old one, nor the new one are marked with T's normally found on vintage dials.
