This 1870 model is in a particularly nice gold filled case. The cuvette has a gold filled inseret that is decorated like a case back. It fits in a bezel like a glass cuvette would.
This watch also has the 1868 patent setting mechanism. This is not listed in any of the Waltham literature I have seen. The standard setting mechanisms are: key set from the back; nail set with or without Fitch's setting patent; lever setting with the 1872 style lever; button setting that, on the movement, is identical to the nail set.
This lever pulls out straight as in the 1868 model patent.
