买SEIKO的人工动能手表好,还是CITIZEN的光动能手表好?
哪个故障率低?哪个精度高?佩戴时都需要注意什么?人工动能和光动能的优劣势?

或者是天梭的低端?纠结中.
但是好像说人工动能一辈子都不用换电池,光动能10年左右换一次,天梭的这个就是用普通的电池啦（当然天梭牌子更好）
反正就要1000-2000左右的,可以推荐.

据我所知,人动电能的10年返修率,比西铁城的光动能低很多.
精度应该没差别.
不过人动电能比较重,因为很多部件模仿了机械表.
人动电能也不是一辈子不用换,20年左右还是要换.
但是看到你最后的心理价位,
我想说,你不用考虑精工和天梭了,
基本上买不到啥了,
人动电能4000起.
