It certainly has a case that looks like the Solid State tagged model you're referencing. The seller kindly responded to a request for more info/photos with the shot of the back and said he had got the watch as part of a lot. It's a strange beast in that it's display overtly recalls the Microma BR style but the back of the module clearly isn't Microma-like. The button at 2 o'clock protrudes in a way that doesn't fit into the usual commercial standard. Who knows, maybe it's some sort of OEM prototype LCD by Microma (pure speculation on my part)? Interesting piece....
The attached shows a Speidel with a similar type display but the alignment of the word "Date" is different and the font doesn't seem an exact match. Speidel never made their own watches but I haven't got confirmation who did, it's possible/(likely?) that it was Microma (at least for this model?)
