in my country, Indonesia there are many watch is built from other parts and I believe it often called franken Watch. most of them are Seiko and Orient. I myself keep a Tugaris "Silver Leaves" that I bought in December 2018 and it works great. the seller said it was from the early 1970s. Actually, both the seller and I cant identify more information on the net and the price is a kind of "agreement' rather than quantifying the value of the watch. If you have any information about the manufacturer, I Will be in debt.
it looks that the bracelet is not the original and the dial has some natural rust.
