picked this one up on the Bay for pretty cheap with a old car clock included and got it running solidly but it kinda has me stumped. It appears to have a full chronograph movement,..but has no way to set the hands, I'm afraid of pulling any harder on the stem to see if it sets it all chronograph functions work. I've never seen a chronograph with a constant running second hand. i marked the staff behind the chrono center second hand and it rotates hourly so i guess it has a spot for a min hand, but i cant see any way you can fit an hour hand in there .Did they make stopwatches with a running second hands at any time? https://www.collectorsweekly.com/stories/235886-realy-cool-aristo-stopwatch--chronograp?
