Case/lug difference between BLNR and BLRO

[liu_watch]

Having watched the recent post containing a video comparing the two watches, I still did not see the difference in the case/lug design of the watches. I think Rolex mentioned about a slight update to the case/lug. Could someone with better eyes or owners of both models explain the differences?

TIA

I don't think the differences have been exactly specified or documented.

And if they can't be readily seen in online, close-up pics, will be negligible on the wrist.

I would say the difference in the lugs is marketing mumbo jumbo between the GMTs. The only change is what ever was necessary if any to fit the jubilee bracelet.
The change in lugs between the old and new Deepsea's though is much more noticeable.
