I am slightly disappointed with the performance of the 8500 - considering the reports on forums has been how great this movement is.
Timing is a bit off - over the last ten days it's loosing -3sec/day - constant variance - not a lot - but it's a shame it wasn't regulated more accuracely - I prefer my watches to run slightly fast if anything.. I find by placing face down overnight this variance can be reduced a bit.
Overall though - it;s been getting a lot of wrist time!
