I think the Speedy Pro and the steel no-date Sub (especially the 14060(M)) have the same "personality" - no-nonsense, works well with everything, top of their respective classes. I have a 14060 incoming to replace the one I regrettably sold a year ago. If I could only have 1 watch, it would be the Sub simply because dive watch construction makes it better for beater duty. If I could only have 2, I would have both.
I had this choice in the sixties when my choice of 21st birthday present came down to a Speedy or a Sub which at the time both cost around 拢65.
I chose the Speedy because I was and still am a motor racing fan and used it for timing in period. Later in life when I took up sailing I did wonder if I had made the right choice but I used the Speedy with no ill effects.
Value wise of course I would be pushed to justify the cost of an 'Ed White' now. I have no idea what a 1967 Submariner might be worth in comparison!
