For me, heat-blued hands are the ultimately beautiful component on a watch's face.Especially wide hands, if possible domed, perfectly polished and of a wonderfully saturated, deep blue, this is what makes a watch perfect for me.
My personal favourites (of which I have none, unfortunately) for heat-blued hands are watches by De Bethune and earlier Dubuis.
Here are a few of my watches with heat-blued hands:
