A once great American retailer. Montgomery (monkey) Ward sold watches under the legant lable.This Hamazawa powered version came with a bad mainspring. After cleaning lubing swapping. this example runs surprisingly well. Don't turn up your nose at a 17 jewel Hamazawa. They are better than you might think.
My advice would be to spend most of that for tools. You already have the stero microscope to see very closely. Taking super high res picture would not fix faults and to get advice on the forum all you need is a regular macro camera even if few years old. Bust surely you need a stand.
