No, I don’t believe that in modern times they’ve done a numbered limited edition of a unique watch available to the public.
That said, with a bit of digging I did come up with some rare instances of modern, numbered watches. A few examples below. Though these examples tend to be not available to the public, and not entailing a unique watch so much as just a commemorative caseback.

The present GMT-Master II is part of an extremely rare limited edition of 123 pieces made to commemorate the famous Sea King helicopter commissioned by the British Ministry of Defense to be used as an anti-submarine warfare helicopter as well as a search-and-rescue (SAR) and airborne early warning (AEW) helicopter.
Produced between 1969 and 1995, the last remaining Sea King variant in Royal Navy service was retired on September 2018. Even if Rolex is known for not doing limited edition or accepting to produce special pieces upon order anymore, the present watch proves the exception. Exclusively sold to those associated to the Sea King and not available for purchase otherwise, the watches were numbered on the caseback next to the Sea King engravings with the words “Fear God Honour the King”.
Numbered 123/123 the present watch is the last one of the batch. It is offered in excellent condition and even if the visible part of the watch is identical to any other reference 116710LN, the breath of the collector will for sure be taken away when looking at the caseback.”

Here there was more than a caseback engraving, but only just:

So, Rolex does appear to have some history of making limited, numbered run commemorative watches, but not exactly available to the public, and the watches aren’t unique in design save for the branding?
