1) The 1st model 17, I have owned 2 over the years, but sold them to collectors
2) The Anniversary Edition model 17, Its a cop out as it was just the current model 17 with badging
3) The Gen 2 1/2 big frames (20 & 21)
...since I already wanted one, and had been looking, this was the choice for me to pair with the watch.
