I recently picked up my first B&R, the 126 Vintage Original (non-carbon), and loving it so far.
However, I noticed that when using the chrono, the second hand stutters/jerks/jumps in a few places around the dial. I know the movement is a 2894 (which is a base 2892 with a chronograph module added on) so it won't function as smoothly as a chronograph built movement. Should it be pretty smooth all the way around or is this just a quirk of the movement? It looks like the stuttering can also be seen on the Tag Heuer Calibre 17 which I believe is the same or similar movement.
Also, is the crown push-pull or screw-down? I read online that it is screw-down but the sources don't seem to be the best while mine is push-pull.
