The Vostok Caliber 2416 is a simple but very robust automatic movement, however, I recommend you to see it "live" (or a similar Vostok 2416 Caliber watch) before deciding on your purchase. Some people love Vostok 2416 Caliber watches for their simplicity, while others don't for exactly the same reason, so it's mainly a matter of taste.
By the way, the watch you're interested in is gold-plated, not gold. You won't find a gold watch for under US$150, unless you are really, really lucky on eBay.
The main problem I have with the 2416 Caliber automatic, and 2414 Caliber hand-winding Vostok movements is that they usually leave the factory not very well regulated, therefore, they tend to be quite imprecise, (anywhere between -15 to +40 sec per 24 hrs.). Due to better QC, and overall quality, Japanese watches usually perform better.
