direi così. Non è che i polsini abbiano il risvolto, ma, essendoci bottoni apribili, non finti, volendo si possono risvoltare.

Alcuni link dove tra l'altro spiegano che il termine è sinonimo di surgeon's cuffs, e ne illustrano il significato.


Although the sleeve buttons usually cannot be undone, the stitching is such that it appears they could. Functional cuff buttons may be found on high-end or bespoke suits; this feature is called a surgeon's cuff.[27] Some wearers leave these buttons undone to reveal that they can afford a bespoke suit, although it is proper to leave these buttons done up.[28] Modern bespoke styles and high end off-the-rack suits equipped with surgeon's cuffs have the last two buttons stitched off-centre, so that the sleeve hangs more cleanly should the buttons ever be undone.

This is a little detail that's grown in importance over the last few years: "Real Cuff Holes". These are seen today as one of the major hallmarks of a bespoke suit. But surprisingly enough, it wasn't always this way. Indeed, when I started in the trade twenty-three years ago, a relatively short time span, real button holes on the cuff were very rare.

However, if a suit is custom made, either "bespoke" or "made-to-measure", since the sleeves have already been measured to the perfect length for the wearer, the cuffs will be what is called "working cuffs" or "surgeons cuffs"; where the buttons can be opened and closed. This may not seem like a big deal, but it does allow you to effectively roll up the sleeves of your jacket when the times (or your style) call for it - which is one of my favorite looks right now, especially on an unlined cotton jacket.
