list of serial numbers for waltham pocket watches

You can see that Waltham (last column) showed rather diminished production from 1914-1917, with a huge jump in 1917. Did he have access to information that has since been lost? Or did he just interpolate more to have a date for each year? (I see quantities that appear too regular).Īttached is a list I have been compiling for some Waltham research I am doing on the production numbers spanning the period of World War I. What makes it so intriguing is that he lists serial number with much more (apparent) detail than any other source. It differs somewhat from the Waltham-Ehrhardt chronology.Ī little known and very intriguing serial number/date list was published in 1968 by Henry Fried in The Jewelers' Circular-Keystone. I expect that this is also the most-used serial number-date correlation, but do we know what the source of his information is? I have the 3rd edition of his price guide, from 1983, and it has the identical list. The most commonly available date list is that published in Shugart's price guide. It appears as if it may have been derived (with one or two errors) from the gray book, with Roy interpolating serial numbers for years in between those listed by Waltham.

It is somewhat sketchy, with serial numbers listed in round millions and not shown for every year, but rather for each million.Ī better known serial number/date list was presented by Roy Ehrhardt in various publications as far back as 1976. The earliest date chart that I know of was produced as a front page in some versions of the gray book, Waltham's list of serial numbers and movement descriptions from 1954. What source do you rely upon for dating Waltham watches?
