On the other hand, the function of the case serial numbers seems to have been for internal uses only, primarily to keep the major pieces together during production and to track the disposition of expensive materials and finished product. While movement serial numbers were used to assist in, and track, production they also needed to be maintained and published for the purposes of movement grade identification, primarily for the obtaining of correct replacement parts. However, Marsh was working on a history of Waltham, possibly with the assistance of Keith at the time the books were prepared.Although a lot can be learned about many American watch movements by knowing the movement's serial number, the same cannot be said about case serial numbers. No one knows why Waltham had the other volumes produced. Watches after 7,500,000 can only be identified from the 1954 book that was intended to allow parts to be ordered accurately. Watches before 7,500,000 can be identified much more accurately as to date of production and size of run than the later watches. One of the originals is at the Charles River Museum in Waltham. The second volume was copied in a small number by Joe Brown a couple of years ago and the copies were sold locally in Boston. The first volume that goes up to 1,500,000 has been published in condensed form by Heart of America Press. This was transcribed in hand in two volumes by a transcription firm in Boston. The second is the 'hand written' ledgers that were created around 1900 by Waltham from the job cards that were on file in the factory. The most common is the repair and identification list that was published last in 1954 and has been reproduced by Roy and others.
