I think it could be a ref 2324 if it has a diameter of about 35 mm - the larger brother with similar case design is ref 2325 measuring 37,5 mm though.
I assume it is the smaller one from what I can read (better guess) on the blurry picture of the inner case back and from the proportions of the case parts...
Dial has the same design as used frequently on the 30 T2 SC Rg chronometers, it is a nice design but dial has aged unevenly and is not in good condition.
just my thoughts on this
