i am am new to the forums and new to watchmaking etc. please bear with me if I trip on something here. Also please know I would not be asking if I hadn't already searched
That said I purchased a bunch of "junk/ loose movements in need of repairs etc in order to practice repairs and amongst them found this movement. It is marked A,A, Hammond but this seems to be a private label that was also found on the dial. It came in a silver salesmens case with no markings. It is an 15j 16s stem wound movement with some interesting demasceneing.
Obviously it it has some unique features such as the nautilus regulator that looks very similar to some C.H. Meylan movements but there is no evidence of the crest anywhere I can see. It also bears resemblance to some Agassiz movements with the regulator and in particular the hair spring mounting stud, but I could find none of those with the more modern winding wheels setup nor with the the balance cock mounted to the right side. It also had a different style retainer for the winding pinion than I have seen on American movements, lastly the winding wheels caps and the regulator parts are finished in a flat iron sort of finish not the typical polished finish on most watches. I suspect this is a finish as the teeth of the gears are polished from when they were cut but not the faces etc.
Some posts seemed to indicate longines made nautilus regulators but I could not find anything remotely even close to this. Searches for Bedford come up blank and it doesn't appear to be a grade name either.
I welcome any any guidance you can share to help me figure out who made this interesting movement.
