The fist 7 "runs" of the 1873 model show a pattern that has some interesting implications.
The first run is all 15 jewel Am'n gade with 970 made between October 1872 and July 1873. Serial number 691971 was also made in Ocotber 1876 in Riverside grade. Numbers out of order like that are often associated with some change that took a while to get it right, but we do not know what it was. This watch was finished just following the Centennial Exposition while Waltham's prize watches were still being tested by Dr.Watson at the Dearborn Observatory.
The group of 6 watches might also have had something to do with the Centennial, but it is likely they are just filling normal orders. the same is probably true of the final 20 watches in this group.
I suspect that the other two Riverside grades were part of the order for the first one. The odd Am'n grade 691979 may have also had some special significance for the centennial

The early production 1873 model also includes two more runs from when the finish was changed from gilt to nickel. I have an example from the 720001 run that was aparently sold at the 1876 Centennial, 720529. I believe the run at 721001 is the first run of 1873 watches with a nickel finish but I would be happy to be corrected.
