This is the classic Rolex fan. Sort of brainwashed and clueless while insulting to others. Both spring drives and grands are more accurate than Rolexes. Beyond that who even cares. If you want accuracy certainly don’t get a mechanical watch.
If you meant Seikos high end products you should have said those, no one calls Grand Seikos just Seiko since they are very different. With that in mind I don't think we disagree very much here.
