Im no expert on movements Athan. If your Asian 6497 serves you well then why spend the extra $80.00? I have heard that the swiss movements (6497) are made where all reps are made, China. This is what I have heard, and it does make sense. Then some believe that they are indeed Swiss made. I dont buy it but thats just me. I will be in the same position soon. I like your Idea of using the extra $$$ for a strap. Good luck with your decision. Mike
