NIcely running ladies Accutron watch. 1973 vintage 10K RGP, running but gains about 10 min per 24 hr. . Need to have it cleaned, some wear on the back of the band to the gold plate. Cannot find an advert, would like to know the model name.
For whatever it's worth, I have 60 + Accutrons in every caliber but 219 and I have five non Accutron tuning fork watches and I run all of them except one 214 on modern silver oxide cells. One 214 does require an Accucell.
Both of my 230's ran fast when I got them but have been adjusted to run accurately on modern cells.
As a follow up.
Tried using an accucell it now keeps perfect time. Within a few seconds a day.
Swapped the 344 back and it again gained 30 mins in 24 hrs.
Pretty conclusive test.
Will leave the accucell in place until I get it serviced. Then I will get it adjusted to run on the 1.5v cell.
