Excellent, do you know what size ETA movement ring I would need? Would it be the same ring for both the 2846 and 2452?
There are quite of few of these movements available on the bay but most are marked 'for parts only' or part of actual watches. I would probably lean toward a donor watch so that I know the movement has not been sitting out in the open, exposed, for who knows how long. Any opinions, good or bad, on using this approach to procuring a movement?
