926075 LIC. ATO (Leon Hatot)

#1 Post by Namespetra » Fri Oct 20, 2017 5:51 pm

Through fellow VWF member Jersey Mo, I recently acquired this like-new 1970s Hamilton electronic watch. I am amazed by its pristine condition - it looks like it was never worn and stored these past forty years in ideal conditions.

The stainless steel Star case is numbered 926075. It runs a 13j grade 683 (ESA 9154) movement. It even has its original 11/16" Corfam strap with a signed buckle.

"SWISS MADE LIC. ATO" appears on the dial beneath the six o'clock marker. I don't recall seeing such a designation on a Hamilton watch dial. I've recently learned that the technology behind this watch's transistorized movement was invented and patented by Etablissements Leon Hatot (ATO). This licensing acknowledgement with ATO sometimes appears on the dials of other watch brands that utilize similar electronic movements. Leon Hatot the man died in 1953 but the Swatch Group, which owns the Hamilton brand, is the inheritor of his designs and name.

Does anyone have information on this particular watch? Has anyone seen the ATO designation on another Hamilton watch?

Nice!

Maybe it's time to set-up a dedicated (sticky?) thread to the various Hamilton ELECTRONIC (not Electric) watches on the Hamilton Forum? I don't think anyone really knows a LOT about them, and since only a few people likely actively collect them, perhaps now is the time to begin to bring all of this information together in one spot? Frankly, I have always kind of ignored them in the past as cheap Euro-trash, but this example is too nice to ignore.

I have been keeping track of these when I have a case number to reference it. Without proper identification, there's not much I can do but file them all in one place for future reference. Here are the pages with the case numbers I've collected. http://www.vintagewatchforums.com/viewt ... 068#p30068

When the model appears in the catalog and we have a name or other information for it, it can be listed in the Master Photo Thread. Here is the page for Electronics. http://www.vintagewatchforums.com/viewt ... 068#p30068
