I have been having the itch to pick up a Vietnam era Benrus. My question is how is parts availability for the movement. The watch uses a Benrus Calibre DR 2F2 which is based off the eta 2370. Are parts still fairly accessible or is it one of those things where you want to find one that’s been babied. The one I’m lookin at is pretty scrapped up and scuffed, which is what I’m looking for. They say it’s in good running order but has never been serviced. Any advice on these.
