The one watch in your collection which you rate having the most historic significance

[cruvon]

Hi, thought this would be an interesting topic, would be a pleasure to see the one watch in your collection which you believe is hugely historic.(read not rare, more like say a watch with huge provenance that was associated with key events in world/human history, it doesn't have to be that ground breaking, could be one that had huge significance through your personal/family history too)
