Forumners, I was walking through a medieval market town when by happenchance, I came upon this Heuer timepiece in an olde shoppe. It was still in its box and appeared unused or at least, little used. Heuer I.F.R. With only two pushers, one of which, also ...
I have many regular chronoscope watches that can display 12 hours of elapsed time with resolution of 1/4 second or 1/5th second or even 1/10th second. Why have a (very) high frequency escapement (sounds like 360,000 vph) if it has only a seconds hand cycl...
While testing the power reserve, I found the gentle buzzing chatter very soothing in the background as I was typing on my computer. It's a mechanical 'white noise' machine! MTF
What twinned fates? What coincidence? Our wills and fates do so contrary run That our devices still are overthrown; Our thoughts are ours, their ends none of our own. MTF Heuer ...
I found that this watch was used by pilots flying Instrument Flight Rules (I.F.R.) during final approach and landing. That way, the aircraft achieved its landing slot. Obviously, 12 minutes is enough for that. The 1 second resolution is good enough for ai...
That makes more sense MTF but not for a direct approach and landings. I have never come across such a specific stop-watch as shown here but in a former life as a transport pilot we used to carry out 6 minute holds (it still happens of course) over aerodro...
chippyfly, Then, a six-minute chronograph makes more sense than 12-minutes with your extra flight information. The power reserve is about an hour so there are at least 10 holding pattern cycles. 😊 Heuer use to sell the square bracket to fix a standard ins...
Were used for management - i.e. for what we would call process optimisation now. For such a purpose second subdivisions were unnecessary. So maybe yours is one of these? A cool find at any rate
