Anti-magnetism haven’t been on my top priority list (since im new in watch collecting), but all me personally look at specs as well when looking for a watch. Started with a seiko 5, price to get into this rabbit hole was my first concern. Then water resistance and size are next.
Agree with you on the ”looks” part, but then case design include lug width and bracelet/strap (ease of bracelet options). And anything polished means less anti-scratch-magnetism.
now im struggling with my first swiss made (hopefully spec worthy diver) and looking forward to give 4hz movement a try.
