thank u man, can i ask one more question. how much time lost is normal for NH35a one month?It beats me why anyone would be so lazy as to want to shower with their watch on, but if you're of that particular mindframe yes, go ahead, it's alright. Just remember to keep the crown screwed down snug!
The NH35a should be accurate. If it is not, any watch repairman can re-regulate it to be so.
