: I just received a vintage stopwatch (not a
: Heuer, it is a Minerva). The hands of the
: stopwatch make a full revolution in 60
: seconds, but the number 100 appears at the
: 12 o'clock position, not 60.

: Curious about the scale and what the watch may
: have been used for. Most stopwatches I see
: have either 60 or 30 at the 12 o'clock
: position.

: Any help would be appreciated.

: Thanks

Tom-
Many of us who were auto rallyists in the days before calculators preferred stopwatches calibrated in 1/100ths of minutes. It made time-speed-distance calculations easier as there was no need to convert seconds to fractions of minutes. The Heuer stopwatches, including the dash-mounted Monte Carlo models, had optional decimal dials. The Heuer pocket chronographs had both 1/100ths and seconds on the dial. I still have the Heuer stopwatch calibrated in 1/100ths and pocket chronograph that I used for rallying.
