My first "vintage" Heuer timepiece

Oct 25, 2018,14:52 PM
 

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 serves as the winding crown, I think it is a chronoscope of some sort.

When activated by the top pusher, a strange whirring sound emerges but the seconds hand moves, well...a circuit each minute.

That minute elapsed is indicated by a jumping digital display.

There are only 12 minutes available on the minute totalizer before it reverts to zero minutes.

Activating the top pusher again will stop the clock and the side pusher resets everything to zero.




Heuer I.F.R.

The power reserve is about an hour, albeit measured in epochs of 12 minutes.

Despite the very fast whirring sound of indeterminate frequency, the seconds are not subdivided nor is there a fractional seconds hand to show 1/10th or 1/100th of a second.

So, it appears to be a 12-minute chronograph with a resolution of 1 second only...

That's all I know...…

But what can you do with it?

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... 

Stick it on ebay ? [nt]

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

That’s entertainment ? [nt]

☺ I need so little

I'm a chap with so little. A bloke with so little needs. I find wonder in little things. 😉 MTF P.S. It's really a soothing sound...

Damn! I've been looking for that for months!

I knew I misplaced it! I'll pm my address, Melvin. Thanks!

You were also walking down the lane with the watch in a medieval market town...?

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 ...  

Yes!

Purpose?

A chocolate teapot comes to mind as a measurement device for short time intervals! Why this watch? Best Clive

I did more research

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... 

6 minute holding patterns

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... 

6 minutes

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... 

Lots of stopwatches back in the day...

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
