2- Additional red strap included
3- Letter colour of 5 respirations/15 pulsations plaques changed
4- Dial marked PuristSPro
5- Numbers, St Gallen, Rescue etc removed from dial
6- One of 4 second hands totally red, not just the tip

8- Minute & hour hands in SS instead of totally white
9- One component of the movement (as is the PuristS way)
