I have been looking very closely at the Aviation Series watches and I was ideally looking for a watch with a LED illumination however that is not a deal breaker I guess. I noticed the GW3500B-1A is the only Aviation watch with a LED illumination but it is the black model with yellow accents. I am looking for a this watch to be my casual/sporty watch more than anything. I am curious of anyones thoughts are on these models and which one they like the best. I am further wondering if anyone likes the yellow accents or do you find a little ugly. At this time, I don't know if I like it or hate it so I am looking for some great advice. Lastly, I had made a post about these watches with illumination and I really appreciate everyones response thus far. It is frustrating because I actually called G-Shock and spoke to a customer service rep on Fri and she informed me they all do have a LED illumination button however after looking on G-Shocks website I was unable to find anything in regard to this. I just assumed at this price point and quality they all would have the LED light for night time however it appears that is not the case. Thanks a million for your help and advice.
