Usually I'm more of a Vostok collector but got this Slava recently
from the fleabay. Haven't seen in any collection before.
It's the usual slava movement with a tiny pusher at 2 o'clock
for fast date adjustment that you can press with a finger nail.
Obviously designed to help doctors and nurses in picking up the pulse:
Start when the second hands is at 12 or 6 and count until 15 heart
beats are done. The tachymeter scala then tells you the beats per
Caution: Might raise the pulse of some collectors !
