I think it a smart purchase. I'll get corrected if I'm wrong but save a scratch to the crystal, I'll bet it can have surface scratches taken out easier than its non-polished brethren. That's my rationalization anyway. Enjoy!
Its a very comfortable watch. Glad I picked it up. With only 150 made im sure it will only go up in value. Plus I didnt pay the 2000k retail that it sold for
