After looking at several threads over the years, I don't think there is definitive proof that chamfers ended on a certain date.

But you should be safe looking at V serial numbers and pre-V.

I'm sure there are G s/n versions that are chamfered - but there is always the chance that the chamfers you might see in a listing's photos were put there by an indie watchmaker during an overhaul and polish.
