1- It seems the 9300 movement was launched in 2011. That makes it a relatively new movement. Were there any issues with early model 9300s? As is the case with the PO8500 and PO2500, there were modifications made to the movements during their life cycles such as 2500A, 2500B, 2500C, 2500D and 8500A/8500B. Is this the case with the 9300? If so, which movement type should I look for?
