RM for trap shooting????

[Big Dog]

Just chasing some tech advise from the learned. I shoot around 300 targets per week ( 12 gauge ) and it definitely plays havoc on my watches from time to time. My search for a good trap watch has led me here as i would feel less naked if i worn no pants as apposed to no watch ( iam sure some of you share that way of thinking ). In olympic trap no electronic devices are allowed so mechanical watches only. I have been considering a rep bubba watson but iam not sure how legit the impact system is on a rep. Also is the 8215 an accurate movement? I am OCD with watch accuracy with +-5 being my general tolerance before breaking out the tools. I have seen some models of the Rafa running 9015 movements but they seem to not get much mention anywhere so i am wondering if maybe they are janky RM reps.
Any advice at all on a good pick would be greatly appreciated, cheers
