Greetings Folks, My friend brought this recent find to my attention, and we are looking for insight on this curious case. Neither of us have seen one quite similar before. It is the Omega shown here, with a contemporary for size comparison. It is a two-piece case, with caseband and center. The center is a snug press-fit into the caseband from the backside. I believe dial has been reworked, and I suspect the crown is of another origin. Based on movement and case serials, I might guess year of origin in the 1939-1940 range. This is an R 17.8 Movement, with the OXG (USA) import code. It seems it might have had fixed bars at one point, which were cut out in the span, and re-drilled to hold springbars. Here you can see how the center fits into the caseband. I found a similar looking two-piece case on page 235 of AJTT, but case style and dial layout are where the similarities end. Has anyone something similar to share, or possible previous sightings? Thank you!
