A picture would really help and are we talking mechanical or quartz?

Edit: just Googled it, it will be a Chinese movement if you know the mm size then https://m.cousinsuk.com/product/watch-movements/chinese-movement-list/chinese-movement-range?_=1487533916810 will list it. Obviously cousins price is 5-10 times the actual cost in bulk.
