Thanks for the replys everyone, my current Gshock receives that radio signal from Fort Collins every night and I have some clocks that do the same. I realized automatics weren't the most accurate and I will probably stay away from them unless I have some serious funds I feel I need to spend. I didn't realize automatics required that much maintenance, which is the reason I found automatics attractive (no changing batteries). Looks like I'll stick with my solar/atomic (radio) Gshock 5600J and get my Invicta adjusted.
Honestly, you don't need to spend a huge amount of money to get an automatic that is very good at time keeping. Buy a watch, wear it daily, keep track of how many seconds it's losing or gaining. If it's too much, take it to a watchmaker and have it regulated. Still, Invicta is far from the best of the inexpensive automatics out there. Actually, Orient has a reputation for excellent accuracy (among inexpensive automatics). Before my black Mako was stolen it averaged +8 seconds. Literally just one second out of COSC. Considering I paid a little over $100 for mine, one second out of COSC was perfectly fine by me.
Just the nature of the beast . . . The cheapest quartz watch is simply going to keep better time than some automatics worth as much as a nice house. And, I'm not exaggerating when I say that. Chances are though, with a bit of care and routine servicing (about once every 5 years or sooner if the accuracy gets way off); a well-made automatic can last decades if not longer.
