How many people in this drop have smoothly rotating blades? My watch looks like the blades are having buffering issues. This isn't good.

thefitzThis problem is well known and does not affect the timekeeping. The more heavy the second hand is , the more likely it will stutter.. Here: http://members.iinet.net.au/~fotoplot/invicta/invicta.html is a good explanation. Apparently a good watchmaker can adjust the second hand pinion spring that pushes on the pinion. If too strong it will affect the "run time" but that shouldn't matter as long as the blade runs smoothly.
It seems that an Miyota 8215 is the wrong movement to carry a disk..
