White Shadow with 14k Gold Case, Japanese Hallmark

I picked up this UG but I'm not sure why the case is 1, white gold, and two, stamped with a Japanese hallmark. Has anyone seen anything like this before? Thanks.

Very interesting and this is my first time seeing the 14k gold case on a white shadow too.

I always thought gold cases made it a “golden shadow”. Nice one.

Ya looks like a dial swap downgrade. People do the strangest things.

One could say u shouldn't discuss taste, but in this case...

I agree, though I've always been partial to UG's starry night dials.

Still, I'd say they chose poorly.
