I thought I'd pose this question for you people who know way more about Omegas than myself. I was looking to buy my first Omega watch and don't know which models are the best value. I was looking at the Aqua Terras but aren't restricted to it. More specifically, the 2517 series or the 2503 series. There is that one major difference of automatic vs quartz that I don't know if it's worth a few hundred bucks more for. Your inputs are very much appreciated.
