I must agree with you Mr. _John, that this sweep seconds/ chronograph (flyback) hands is not perfect yet.
Dont you think it is also pretty mis-leading to collectors who might have interest in buying this watch or may be the new nautilus chronograph ??
Does this sweep seconds/ chronograph hands also apply to the nautilus ??
When the 5960 was first introduced, i thought this sweep seconds hand will internally correct itself after the chronograph is not in use, "since it doesnt really decrease in the power reserve nor cause any additional wear and tear to the parts" stated the article.
Since i have not the actual watch, i wanted to understand a bit more, the AD's i have asked, some doesnt even understand the question.
I am glad someone out there can clear this question for me, I thought i was nuts. 
ooops, wrong picture !! Ha !!
