I am looking to buy my first Tag. All of the watches I mention will be quartz and probably all late 1990's models. I am looking at a 4000 series and a 6000 series at approx the same price. Both have paperwork and in at least very good condition. The 4000 series has been regularly serviced. The 6000 series is unknown as far as its service history. I really like the look of the 6000 series, but I have read that the bracelet breaks and replacement is expensive. I also have my eye on a Kirium. It's in good condition and said to be maintained. I really like the look of it as well. And I have the opportunity to buy a 2000 series for $250. For any of you out there, what are your thoughts or suggestions? Would you have serious reservations purchasing the 6000 and is the bracelet issue with it a serious one or do all Tag have a similar problem> Thanks!
