Yes, these should be in the Master Reference Table. At some point, we do need to update those tables, but it is a big job. The gentleman who did most of the work in writing these tables only covered certain years, and he was driven by what was in the catalogs; I am guessing that your chronograph was from before this period.

Great story . . . can you show us this very interesting engraving on the back of the watch?

Thanks,
