Gigatron

Hey gang, I'm new to this whole rep watch arena. My reason for even getting in was that I needed a decent looking dress watch. Since I work in server cabinets all day long, I wear a beater luminox during the work day, but I wanted something nice for going out on the weekends. Anyway, I settled on a submariner from Andrew. I ordered it Sunday and got it on Friday. Since account upgrades are closed for now, I'm having some problems finding all the info I can. I'm not familiar with all the board shorthands and abbreviations like TTK or MBW or any of those, so I don't know if I got a good deal or not (since I can't seem to decode half the posts I read). So, did I get a decent watch or not? Are there things that are known to be glaringly wrong? Things that can be easily recitified? Over the long run, how accurate is the movement (swiss ETA 2836-2)? Thanks, Fred
