Here we see that the back edge of this SBGY003 hour hand not only has crisp edges, the side surface is finished without visible artifacts; the pattern you see there is a clean reflection of the watch's face pattern. Note that things aren't completely pristine here, though: this is a real-world photo of the watch in that you can see how the bottom of the second hand is finished in one reflection, and can see a bit of schmutz in another. jbm-20200819-sl2-023
