First, I want to apologize if I mislead anyone on the hex size, as I said the number I had was for the gen, I assumed it would be close but apparently not. Would be nice if they threw in a couple of proper sized hex keys for the price.
The rule with reps is ALWAYS tighten every screw and watch them closely for a few days with Loctite 22 handy for any that want to back out even when properly torqued. In the end it is hard to avoid hardware loss, I noticed a "cap screw" on my PO GMT bracelet was missing even though I am anal about checking and monitoring screws. Fortunately, I have plenty of extras on the links I took out.
