I own one Orient automatic diver watch with date. self winding, non hacking. Its rotor wobbles alot, which sometimes is fun to hear and feel. Sometimes I just like to shake it and feels its wobbling. Its power reserve last about 40 hours. It's lume is really weak, nothing to shout about. The built is quite and it wears comfortably on my hand. Accuracy is acceptable for normal use, i think it is -15 +25. The price is very affordable and I think Orient watch is value for money.
