What years and models where the blind mans dial used on? ref: This ebay listing

Frank

They were used on the higher jewel count/ higher grade watches. An estimate would be 1910 - 1940. They came in this standard BM style and a monty BM style.
You find them mostly on 992, 992E, 950 and one 950E in the montgomery style.

The first appearance of the BM dial in the 'timebooks' seems to be about 1918...

I think I posted a scan of the timebook in another post... here or on the nawcc board...

we know of some four-footed versions, but suspect they are a "material" dial from hamilton used for replacement on earlier movements...

Here's the B.M. dial from 1915 which supports Charlie and Terry's comments.

EDITED- It had been determined that the below page is from a 1918 era Hamilton "Timekeeper", and not from 1915 as previously thought.

thanks Robert.... a bit earlier than i thought...

someone have their timekeeper handy to tell how they are dated?

the timebooks usually had calendars in them.... two to three year span...

I had seen these on 946's and I think the last run was 987000. This dates to 1914-15, so it seems it could have been at least that far back.

Lindell,
We may indeed be talking about the same book.

Is this the same letter that is in the 1918 book?

Robert

Thanks Guys for pointing out my error.

Sometimes it looks like a Duck and sounds like a Duck but still isn't a Duck.

Below is a list of 12 movement examples shown in the “Timekeeper”
and the dates they went to the “Finishing Dept".

According to Don these would have been completed
in about one to six months.

It appears they used pre-1915 examples in the 1918 era “Timekeeper”.

(Zero's were added to start of serial numbers to keep columns straight.)

interesting....

especially the 960...

but is/could it be true that the artwork was carried over from earlier versions or it was 'stock' artwork from the time books?

I have a 'couple' of timebooks or other publications that have penciled in 'changes' for text, etc... (these were from hamilton i was 'told')

if there was not a directive to change text/image, it was carried over to the next version....

Terry,
I was just looking at the 1921 version of "Timekeeper" located in the "Technical Library, Serial Numbers and Site Links" forum and it appears that the first 14 pages of these books are the same which is just general information.

When you get to the catalog section that is where things change.

It mentions WWI (1918) so it obvious that it is post-WWI.

Do you know if they printed new books each year?

Sure would have been nice if they would have dated these books.

Couldn't agree more !!

Indeed, the reference to WWI is a clue... just part of the puzzle eh?

Fun ain't it.....

I have been wanting to find out what model this dial is. It appears to be a BM model but it is only single sunk. It came on a two tone # 3 case.
I have searched far and wide but have never spotted one of these anywhere.
I am sure, by the previous postings, that this very well may be much earlier than the watch, but I'd still be interested to know.

Mike

have u removed the dial and examined the back?

this could be the 081 dial, which hamilton made when they started having trouble with the DS dials cracking in the early 40's....

care to post rest of info on your #3? movement, case serial #'s?

Terry-

Thanks for the info. No I have never taken off the dial. I can't do that.
Below is the information that I have for the watch above:

movement serial # C163998
CASE serial # H790901
Dial - 50-090 BM SS 24-Hour Enamel

Somewhere in my notes I gathered the information on this dial. I am not sure where that came from though.

Thanks...

I can assure you the dial is not 50-090...

That is a Single sunk dial with 13-24 inner chapter markings and "cpr" font hour markers...

i am looking at the blueprint as i type.
