At least in a pair of occasions, this movement has been used for strange "two hands" modifications.
Being the movement based on the 2409 components (in the same way the Poljot 3105 is totally based on 3133 plates, even keeping the holes for the chrono bridges), sellers of those watches added the central seconds hand and pivot (with its blade spring), synchronizing the central hand with the subdial hand, or "opposing" it by 30 seconds (when the central seconds hand was at 0 seconds, the subdial was at 30 and vice versa). So they were sold as "rare watches with two hands" :-d
Volmax officially used this "two hands" layout on its Shturmanskie Sputnik 2007 reissue, although the "central hand" was a rotating disk, not strictly synchronized with the seconds subdial.
The curious think of the Vostok 2403 and Poljot 3105, is that you can see through the hole left by the removed central hand. I have a Moscow Classic Polyarnik with glassback, so i can see my finger pressed on the caseback if i look at the center of the hands! :-d
