·I would assume a UG case has UG stamping
Interesting discussion with a C24 seller regarding this watch: https://www.chrono24.nl/universalge...mpur-prototype-40-mm-oversize--id27803182.htm
He insists that this is a protype case. Case is unmarked which makes it (IMHO) very unlikely that it is a UG case.
My thesis is that it is a movement of which the gold case was melt and a generic case was added later.
The movement is numbered and - picture is not very clear - it seems to be either 167k or 187k. In 187k I don't have any 287's which had a gold case. In 167K I have have 3. 2 ref 12512 and 1 ref 12539. All with 811k serials.
Curious to hear what the others think.
but yes, normally it should be marked , at least inside if not on the outside of the case back…
