i bought the 7750 version, i think ... please explain? i still have not contacted the seller because the watch seems to be getting slightly better. i have been winding it and wearing it at night etc and it is holding a reserve of about 5 hours now. still not good but certainly better than 2 hours. i just can't be bothered trying to explain this to a dealer that cannot understand english very well. i have had great experiences with her in the past, simply because it was payment and shipment. but at the same time, there were no problems during these transactions. e-mailing back and forth for over a month is very frustrating. anyway, we'll see what happens. all the best!
