First, let me just say that I don't have a dog in this fight, so to speak, as I don't own an NSA. I also don't buy into the idea of LEs for any brand. There are two things I consider when buying a watch -- 1) do I like its aesthetics/mechanics and 2) can I afford it. The rest is more or less marketing IMO.
Sorry you feel unhappy about this situation, and I hope you can continue to enjoy your NSA despite the fact that there are now other editions of the watch.
Best,
Daos
