1960s Heuer Rally Stopwatch Swiss-Made Rare

Rare vintage 1960s rally stopwatch from Heuer. Made in Switzerland. “Note: reads to 100 on main dial. Designed to register time in decimal mode, the main dial is separated into 100 increments, though a full revolution takes 60 seconds - so 1 minute 15 seconds would be registered as 1.25 minutes. 1 minute 30 seconds is translated as 1.50 minutes and so on. Original users tended to be rally drivers and other motor sports types as it is easier to calculate time in decimal. So this is ideal for historic rallying. A second sub-dial above center registers minutes elapsed up to 30. A slider at the 11 o'clock position starts and stops the timer. A press on the crown activates the flyback to zero.” Overall excellent condition with minor wear and keeps time nicely.
