Again, Seiko Bullhead Black Dial

I still collect Seiko Bullhead , especially if I find it in a very good condition. Last week I found a Seiko Bullhead with affordable price (fair price). Its dial and casing are not the best that I have ever found. I still have another two Bullheads which are much better (dial and casing), but this time its movement is the best. Its power reserve is very good, its acuracy is very good, even when its chronograph is on. Over all, its performance is really good. I believe many collectors here have Bullheads, but not sure about the movement.
