I have a couple of modern Hamilton watches, including the Khaki Field automatic (42mm) which has the H-10 Swiss 80-hour movement. It's a hacking watch, and keeps very good time. It gains about 20 seconds a month, and is the date-only model.
I wear it most of the time, and I think I've had it about two years or so. It's had the occasional wetting, but I don't immerse it, as the crown isn't screw-down. The crystal has withstood a fair amount of abuse without scratching or marking.
All in all, it's a good watch, and although the prices seem to have risen somewhat since I bought mine, represents value for money. I should think the same can be said of the King auto, which is very similar to the Field, but has a day-date 80-hour movement.
