Hello, first time poster. I’m looking for any information regarding a Heuer Temponoom Stopwatch. All my research has resulted in little to no information other than it may have been a limited run in the early 70’s. It was a gift given to my father around that time frame and we are both curious of it’s background. It has been well used and appreciated as you can tell be the pictures. Any information would be appreciated. Thank you in advance.
