·Coming up for auction at Dr. Crott another early one with Movm. No. 29600924, Ref. 145.022-69, Cal. 861, and it says ; origin Swiss but since there is no EoA i dont know if that means made in Swiss or sold in Swiss. Lots of aging on the hands and bezel - the caseback looks a whole lot better.... Is the writer of MWO book present here as we now have at least two posted outside of the 31xxxx range ?
Besides the serial number, two other features raise questions. This has a DON, which the SW A-11 didn't have. Also, the case is really chewed up from a hard life. As you noted, the caseback doesn't match the condition of the case. (That sunburst is wierd too.) Without an extract stating that this was sold in Japan, I would not believe it to be originally a SW A-11. Even with the proof of coming from Japan, it's very suspect, IMO.
