here is my daily driver when i bought it and below it is 4 years later on an aston martin deployment that it lives on now.
I was concerned the newer 8900 PO would be a bit too tall on a nato. All my other watches ride on natos, but with the PO I have been hesitant.
This has been my faithful holiday watch since 2007, I'm wearing it right now and it has still never let me down
