Hi all, First post here. I found a UG with a calibre 138 movement that is cased in an asymmetrical Polerouter sub case. I did find it very unusual and asked the seller of the watch how this "franken" watch happened, because it seems like I can never find something remotely similar during my search. the seller replied very honestly that he originally purchased it from a Swiss eBay seller who said it was a prototype, although he did not mention further on what exactly the prototype is. It looks very cool but the dial might be refinished, crown and bezel might also have been replacements. Any thoughts or advice on this would be very welcome. Thank you.
