Go for it if you think he would not enjoy the 'experience' of the automatic enough to justify the lovely experience of setting the watch every once and a while. To me, setting a run out watch is part of the fun. Part of the appeal. I have owned a quartz AT (2500 gen with blue sunburst, ref 2517.80 I think) and it was a GREAT watch that garnered a ton of compliments, now my 15 year old bro wears it as a beater and it's rock solid.
Just weigh the pros and cons and whatever movement you get will be fine, but only you know what your father would really prefer. My dad would go automatic, but he is a watch aficionado.
