Pictures first:





Saw this when I was looking for something else on eBay (isn't that how it always goes?). Based on the measurements the seller listed, I think this is the 31mm version and not the 36mm one. Looking at the (admittedly not great) pictures compared to my SM120, I don't see any red flags in the available pictures. Would still need to see the movement and case sides. Anyone care to offer thoughts? Current BIN price: $1650US. I'm not looking to buy this one (not my color), just thought it was interesting since you don't see these pop up very often.
