Junghans 10th Second Process Time Meter, Hand Winding, Original Box

Ingenious design and well manufactured Junghans 10th second Process Time Meter or in other words, a stopwatch. The watch is a vintage dating to late 1950’s to early 1960’s

It has a perfectly symmetrical dial with the minute and seconds counters matching each other as they both read from 5 to 60. Usually stopwatches are thirty minute elapsed timers, but this one is sixty. The 10th second is in the lower part of the dial. When the chronograph is running, this spins fast to record 10th second intervals. Due to the limitations on mechanical watches, the hand is unable to complete a 360 degree rotation in a 10th of a second. So as a solution, Junghans have put three hands on a single pinion. This is why the sub dial is partially covered so only one hand is visible at a time. Once one of the hands disappears behind the 9 marker, the next hand appears at the 0 marker. This is a simple clever way of building a 10th second stopwatch with a hand spinning at a mesmerising speed

Running well, chrome finish case, clean white dial, lovely contrasting blued steel hands and comes in the original signed box. Real quality, well made, well designed, and typically Germanic in look and feel.
