This is my first "nice" watch that I've ever bought (other than my Luminox Navy Seal which I wear as a daily watch). Two questions for the forums (for now): 1- Is there a place to learn about the difference watch movements and which ones are the best/better ones? I think mine has the Swiss ETA G10.211. 2- Also, I have the model 5559, but there are 2 or 3 others that I've seen that look identical (color, everything) like the 12025 and the 12016. Is there anywhere to find the differences between these seemingly similar looking models?
