Uhm, I may be wrong but I believe he was talking about the online companies who rejected the TS. Or at least that's what I first thought when I saw the post.
I'm a little confused by your post, your saying that you tried to purchase a Marathon GSAR watch and were told that they could not sell to you.
Are you located outside the U.S.? Do you feel that you were denied because the watch's are primarily produced under contract for the military? Or do you think it has to do with the use of tritium for illumination or what?
I currently own both the TSAR and GSAR and both models use tritium for illumination. I use the TSAR as my primary dive watch and I am more than satisfied with its performance. I ordered both watches from the guys at broadarrow.net with absolutely no problems, and did not need to present any type of .mil credentials or anything like that.
