If you can only choose 2 watches (one automatic and another manual, each below $6k) for the rest of your life, what would it be? Ok if you want to, you can unlimit the cost.
For me, the manual would have to be Omega Speedmaster Professional "Moonwatch" - it is just iconic, rich history behind it, can be dressed up for formal or dressed down for casual, great dial layout of chrono at 3,6,9 format. If it is good to go to the moon, it is certainly good enough for earth
The automatic would have to be Ball EM II Diver Worldtimer - very well designed worldtimer complication with day/date and rotating bezel as well. Solid at 300m WR and antimagnetic. Tritium tubes. I cannot find any other watches with so many complications, features and solidly built.
With the 2 above, one for the moon and another for the sea, I think it would cover basically every possible need that I can think of. What is your 2 watches?
