Mikrograph Stopwatch query

Dear All,
This stopwatch has been passed down to me. It belonged to my great grandfather who I believe was given it in the 1920's.
Does anyone have any information on it - date? etc.
Any information gratefully received.
Chris

Don’t know anything about stopwatches, but believe this is a Reference 601 based on the 1936 Heuer Catalogue the page from which is below.



Take a look at onthedash.com for more catalogues from the era.

Hope that helps. Great piece to have received with a long bit of family history attached. Lovely.

I just remembered that I’d seen some Mikrograph info on a document I received from Tag Heuer for a vintage watch event. It was not relevant to the event but was text to provide an example of the info required for my watches, so assume it was from another event.

MIKROGRAPH
1ST STOPWATCH ACCURATE TO 1/100TH OF A SECOND.
The accuracy of the timing instruments at that time was of 1/5th of a second. This Heuer innovation revolutionized science, industry and watchmaking.
Mikrograph made Heuer the natural choice as supplier of timing instruments for the 1920 Olympic Games.

Where yours fits into this timeline I have no idea, but the piece that was written about was from 1916.

Gambba, Thank you so much for your reply.

Yes, I think you might be correct with the date. (the dates remembered by our family and passed down are maybe not accurate). The image on the 1936 catalogue you posted is the first image of a Mikrograph face I've seen with no "Heuer" logo on it. It also has "Swiss made" rather than "made in Switzerland" at the bottom. It all matches.

Thanks again, I'll take a look at the website you've suggested.

I found more info online and seems that 1920 isn’t unreasonable for this model. It seems maybe this same model as yours started in 1916 and carried on for many years.

Here was one for sale previously for a decent sum of money: http://chronocentric.com/forums/chronotrader/index.cgi?md=read;id=27516

I think with having the reference number now you should find a wealth of info that can be found. Enjoy the research.....it’s the best part of any vintage watch.
