I got the new 43mm some days ago and i can say that it is the closest rep to gen i've ever seen.the only flaw are the missing eta engravings on the A7750.
No...it isn't the noemal life of the a7750...it will last as long as a gen 7750 if maintainance is good.Let's have a cleaning and lube from watchsmith and it will be fine for long time.
