I have the Reactor Gamma Ti. What a great watch. I know some hate on Reactor but I've had this thing since about 2012 and have put it through hell and it (almost) never fails.
I think they are overpriced by a couple hundred dollars but if you can get a good deal on one you like they are worth getting.
My clasp did break a while back. I sent it in for repair and true to work they had it back in my hands in 4 days after I sent it. Great customer service.
