Good jobb cornerstone its true that I have to stop linking like that
"The first ever Timex watch, from US Time. The US Time Corporation had been making clocks with the "Timex" name for a short time before this, but the Timex name first appeared on a watch, in this prototype model. During the war, like most other industries, the US Time factories were converted to war production. Civilian watchmaking came to a halt. According to the well-researched book, book by Kathleen McDermott, Timex: A Company and its Community 1854-1998, "In October 1945, after using this name on a small trial shipment of nurses watches for a year - the very first time that the Timex name appeared on a watch - US Time received official rights to trademark 'Timex.'" I have confirmed with Mr. Carl Rosa, historian and curator at the Timexpo Museum in Waterbury, CT, that this is indeed the watch.
It is interesting: Based on the McDermott research, the watch appears to have been shipped in 1944, probably made that same year, or maybe 1943. There was no civilian watch production at US Time, and presumably a watch designed to be worn by nurses was considered to have been in the vital interest of the war effort. Well, not a military watch, but definitely a wartime production watch"
