Hamilton 940 Markings Question "Click" to Login or Register

I'm sure this has been discussed 'ad nasium' in the past, but I couldn't find anything in a search, so I thought I'd toss it out again.

Is there any significance to a Hamilton 940, built in 1903, to NOT having any significant markings other than Hamilton Watch Company, 21j, and adjusted on the movement and nothing else?

I've seen them with every kind of markings imaginable, but not one that's as basic as the one I traded for last Sunday.

Nothing else remarkable about the watch. It has the single script 'Hamilton' on the single sunk dial, and is in a sterling silver Dueber case....but nothing else marked on the watch. I had to look up the number before I was even sure it was a 940, but sure enough, it is.

Is this just a basic 940? Odd? What?

Like I said, I've never seen a movement so 'un-marked' before myself, so I was curious.

Regards! Mark

This might answer your question.

To begin with the 940 was apparently first produced in 1898 with a run consisting of 48006-48300 during 1898-1899 production. Interestingly numbers 44001 and 44002 are listed only as "21-Jewel, Open-Face" in 1898 so they may have been "test" movements. Prior to that we find runs with both the 941 and 943 Hunter movements.

Back to specifics on the 940 grade, I can report that movement number 48727 which was the 721st numbered Grade 940 blocked in 1898 production records is marked as "Hamilton Watch Co., Lancaster, Pa." centered on the barrel cover with "21-Jewels" at the far left. Both "Adjusted" and the movement number are by the balance wheel and "Safety Pinion" arched by the center jewel. Additionally, number 48727 has "Hamilton Watch Co." on a Double-Sunk Porcelain-Enamel dial.

This is difficult to research without your movement number but by 1903 the 940 movement markings should be essentially unchanged. That is based upon number 461702 from 1905 which has the same exact markings as reported above. Beginning in 1906 the Time Inspection Rules mandated among other things that the Grade be shown on every movement accepted in Railroad Time Service and as an example 477985 from 1906 production has "940" marking on the far right edge of the barrel cover.

Looking at the "fully-marked" example number 937323 in the link Tom provided above which is 1912 production, they would take it only one step further. In closely checking number 1448165 which is from the final 940 run during 1927-28 production we find "Made In USA" placed in one of the only spots available, in a circular pattern around the left barrel cover screw. Interesting 940 variants include gold-plated hardware on some movements and even a few two-tones such as shown in the image below this post.


Number 473008 is a Two-Tone "Special" from 1905...

Ooops, sorry about that. Eek

The serial number is 254503.

Yep, like I said, I KNEW this subject had to have been hammered to death by now, but at first attempt I just couldn't shake out the information.

Thank you all for your input! I am now illuminated! Smile

Regards! Mark

Mark,

The watch you have number 254503 would be the most basic 940 marking. It might be interesting to assemble a collection consisting of one 940 of each marking, no less than seven distinct variants (without considering those marked "Special" or "Extra" or any of the Private Labels) which would be an interesting history from the 1890s to the end of 18-size production in the late 1920s time-frame.

One the most difficult to find was from the last production run with "Made In USA" markings as mentioned above. A couple of those "angry boys" told me it did not exist on 18-size watches. So in order to refute their position, I submit the image you see below this posting.

Be well my friend,

Lindell

As a follow up....Chris sent my 940 back to me last week, and it is running, but apparently a 'blacksmith' got hold of it long before it reached Chris' hands.

He was able to clean it and install a new mainspring, but he tells me that there is rust on the hair spring, and apparently some clown in the past decided that glue was the best product to use to hold several items together on the balance. Mad

He was able to clean most of the glue off the parts, and it's actually running about 20 seconds slow per day, but only with the replacement of the hair spring and a possible new staff it will ever perform to any kind of railroad standard. I'm ABOUT to touch the regulator to see if I can pick up those 20 seconds, as I don't know what will happen to that hair spring. Frown

That said, though, it's soldiering on in my pocket as we speak, and for a carry watch, it's still trying to do it's best to perform the duties it was built to do.

Most folks would recommend I just dump the watch on ebay and find a better example....but for some reason I always root for the underdog. It has honest wear, and is in it's original Dueber sterling silver case...though worn, still serviceable.

Sad, but at least it's alive again.

Regards! Mark

This is a continuation of an old post. I recently bought a 940 number 1444800 that has the "Made in USA" around the left barrel plate screw, I'll show it below this post. It appears mine was in a run shortly before your run Lindell. One of our members currently has a movement for sale on ebay that has an earlier number 1440196 but is not marked. I put the ebay listing in pitfalls so look for it there if you are interested. I was trying to determine when these were actually started to be marked as such. It does appear very few were so marked.

After looking at the numbers it appears the last two runs included movements marked with the "Made in USA" but not the 3rd from the last.

My movement number 1444800

To follow up on this old thread, that 940 of mine is long gone, traded to a friend who just wanted an example in his collection and could care less how, or even IF, it ran.

Oddly enough, I have not run across a single 940 since in my ramblings around antique stores. They just dried up in my area of searching.

I had forgotten that watch until you brought this thread back.

Regards! Mark

Mike,

I have a suggestion to make in reference to the "Made in USA" markings.

We find this interesting marking on your number 1444800 from the second to last grade 940 run consisting of 1444001-1445000 during 1923 through 1926 production. And as previously noted, it appears on my number 1448165 which is from the final grade 940 numbered from 1447001-1448200 during 1924 through 1928 production but NOT on number 1440196 which is, as you stated is from the third to last run, we can perhaps extrapolate the following...

It is reasonable to believe the final two runs were likely all marked "Made in USA" unless we find others in the 1444001-1445000 run without this marking. Remember, they did not necessarily complete their movements in chronological order. It is also conceivable that some of the highest numbered movements from the previous 1440001-1441000 run may also bear the "Made in USA" marking, only further research will reveal the facts on those, one way or the other.

This is part of the fascination we have with our wonderful hobby.

Be well my friend,

Lindell

Mark if you go to the bay and type in a search for "Hamilton 940" you will most likely get bored looking at all the 940's. A great watch but very common. The Hamilton 992 is another great watch that seems to be very common on the bay. But buying off the bay may mean you end up with another glued watch.

Oh, I know. I'm talking about finding them in antique stores. They're just not as abundant as they used to be in my area. That glued watch CAME out of a shop, so it's just not on the 'bay you find those monstrosities!

Regards! Mark
