Upgrade a Lemania 320 to a 321

[gkmaia]

Do anyone know if its possible to upgrade a lemania 320 movement to a 321 and add the 3rd chrono hand?

It would appear that it is the same as the omega 320 and 321.

the difference being in the minuite wheel jumper   see attached sheet .  There is also further information on this link  http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&Omega_320.          cheers
