new escapements are one of the pinnacle of the watchmaking art and I absolutely love to see what new stuff watchmakers create!! I do not know of any other watch with a robin escapement but there are other watches that do have "similar" escapement like the one recently released by Grand Seiko,
Brivet-Naudot Eccentricity, Tanzehua Di-axial Escapement, and Logan Kuan Rao Unipush Escapement that follow some aspect of the Robin Escapement but are again very different, Please find below some pics!! Thanks again for sharing!
