rick,
many auto of self winding watches have a "power reserve" where the watch stores the kinetic engery produced by movement, about 36 hours or so. once the reserve is reached the mechansim simply by passes any extra "winding" within its complex sets of directional gears.
there is no danger whatsoever from "wearing" the watch too much and over winding it from kinetics.
in fact the only "danger" is
not wearing it enough. it is recommended that you do not leave the watch sitting still for over a few months as the springs get too relaxed and the oil inside settles and begins to "clump". note that this is still relatively minor and these things with the valjoux or ETA (the 2 major swiss movement manufacturers) movements are pretty bomber.
watch winders are great for those who own several automatic watches, as they maintain lube consistancy and work the springs.
quality winders cost about the same as your watch did. then again, i think this watch could be the beginning of yet another addiction.

most automatic watches are good to +or- 3 per day.
while quartz watches will always be more pin point accurate, there
is that little problem of the batteries....
automatic watches are the way to go, in my book. a lifetime of self reliant service.
you may want to get it "cleaned" after a few years at a quality watch repair or service center, but that's about all they will ever need.
btw, i found a legit source for the alarm chrono at 40% off the retail. still waay too much for me afford right now, but 2800 is much better than 4700.00.
someday...
enjoy your new fortis, you're going to love it.
