I was cleaning drawers in the garage this morning and found this Hanhart timer. Back in the 70s and 80s, I used to run a lot, both distance and wind sprints, and found this was a good way to measure my progress. It was, as the dial says, made in Germany. The second hand makes one circuit in 30 seconds and the minute hand one circuit every 15 minutes. And it will continue until unwound, which was longer than I could keep running! It winds from the back and still works perfectly. The back says it is shock resistant and anti-magnetic. I imagine the timers today are almost all digital...
