Strange how this photographed. The face is dingy and really needs a professional cleaning, so the photo got that right. But what it misses is that the crystal is really four straight facets, rather than a single plate. You can kind of make out where the facets meet because the 3, 9, 12 and the subdial are doubled-up. Some day I'll try another photo that will show the oddball crystal better.
Other than that, it's a nice-enough winder, but nothing special.
