Re: That is a very interesting distinction. I wonder if Heue
Ref Heuer Alarm Wrist Watch. In the Watch Time Magazine - Collector's Corner, was an article about Wrist Alarms. There were almost 40 Calibers and around 200 brands.
Production of these watches reached about 1.5 millions. A.S. (Schild) delivered more than 781,ooo caliber 1475 and 1568 (upgraded version with date) when production finally stopped in 1970. The list is quite long , but no mention of Heuer. In 1969 some Automatic - Selfwinding models came on the market, among them a Nouvelle Lemania with caliber SL 980.
It is very possible that Heuer had a very small production run and did not make the list. The brochure certainly leads one to believe that Heuer produced a Wrist Alarm.
I send this article to JEFF and he can determine if he likes to include it in the blog or another section for all the collectors interested in Heuer. Take care.
