is the waltham grade 235 size 12 double roller or single?
sn 23121194

I'm pretty sure it is a single roller... I will need to check my parts bin to verify... but am pretty sure the one I had open last week was a 235 and it is single roller.

Thanks

Peter,

The movement I had open last week was a grade 1235... The colonial version of your 12S.

It is a single roller movement.

waltham did not make many double rollers in size 12
