Jerky / Jumpy Second Hands & Chrono on ROO 42mm?

[ColdFusi0n]

Hi everyone need some advice. Got myself my first 42mm ROO (Volcano) and wondering if its normal for the second hands @ 12 to be a little bit jumpy / jerky?

Absolutely no problem with my power reserve and the watch keeps accurate time even after 3 days of not winding it.

However, was staring at my watch today and notice the second hand is a little bit jerky. Like there are tiny gaps between the sweep. When i start my Chrono, it moves in the same momentom as the second hand, where the sec hands jerk, the chrono does the same.

I was wonder if its absolutely normal or if there is something sinister happening to my movement.

Secondly, on my wrist i can hear my rotor sound. Is that normal too?

Thanks for the kind advice.
