Assuming the tritium (half-life 12.3yrs) on my watch is fully spent by now (circa early 1970), is there any ‘common’ replacement option to provide luminosity again without changing hands or dial?

Ps: you folk are getting too addictive for my curious mind, every time I read latest posts I learn something new and/or want to!
Thanks for being such a good bunch

Only joined as I was bequeathed a quartz Seamaster Omega, now bought a second automatic and keep resisting impulse to go for another (Like look of pie-pan face ones).

Get thee behind me, Satan!
