I was able to use all three hands from my UPO (after modding my UPO with mod parts) onto my 42 PO v4. The only thing i had to do was snip the second hand as it was a bit too long to fit properly in the case.
Previously, I had an orange insert on the watch but switched it up to green. I kinda did the green a bit more than the orange, but come next month, who knows, I may switch it up again.
