All my warranty are direct from SCUBAPRO USA... the only issue is distance, need a little time. 
so that means this is a USA set then?
to my knowledge the regulators are coded via the serial no. to determine the region in which the after sales would be handled.
i know this because I own a MK25/X650 Europe set and had to send it back to europe for the recall.
all communications and shipping was borne by me!
the local distributor sealantis REFUSED to help because i didn't buy it from them
