Waltham Serial Number site
Our Waltham serial number look up site has been down for quite awhile or at least I can not access it. Do we have another site we can use to get information on a Waltham as far as grade and total production. I do not want to use the pocket watch data site as a lot of the infor from there is iffy. That site says only 300 where made but another site I checked shows the same model with a lot more being made but it doesn't list the serial number range mine watch in question is in. The serial number is 2634109.

Thanks,
Harry

Harry - What model is your Waltham? According to Waltham Serial Lists, this run (2634001-2634200) is designated as a Model 1877 Grade No. 35. If this is true, the total production is indeed 300. If you find your model to be classified as a Model 1883, the estimated production numbers will obviously change.

Keep in mind these resources are only as reliable as the original records available. The Waltham factory records are notoriously inconsistent.
