The serial number of this 4992B is 4C4177. Can anyone tell me what year this watch dates to.

Thanks in advance,
-Steve

i can tell you 4C30922 was shipped in july 1943, so one would assume it would be after this...

Lindell,

Thanks for the insite, unfortunately someone beat me to it :-(

Is there anyway to decode the serial no. on the back of the case? In this one it is AC-42-3379.

-Steve

sorrry i misread the number............
was reading at 41,000

what is the contract number? and any other markings on back?

went to the auction ...

contract number W535 ac 22375 ...

Is a 1942 contract, but i have not found the details of the contract...

have a listing for 3040 movements shipped to Patterson Field in Osborn Ohio @ $29.45 each, and another listing for 755 movements at the same price to Fairfield Airport in the same town....

I believe the 3379 to be the sequence number of the watch in this contract....

The markings on the back are:

AN 5740
MFR'S PART NO. 4992B
SERIAL NO. AC-42-3379
CONTRACT NO.
W535 ac-22375
HAMILTON WATCH CO

It would be interesting to learn how to decode these markings.

PS - I see that Terry added information above

i have not figured out the contracts quite yet....

in scanning them, there are more 800 silver cases than one may think...

Does anyone know the approximate range of serial numbers for movements marked "US Govt"?

Eh..... confession time.

I "snagged" that one Steven. I had lost a couple of them... that said "US Govt" on the movement and I was determined to get one. I wasn't aware of the date-thing. Sorry.

If it was your burning-desire to acquire that one or you need it to complete a collection, let me know. We can talk....

Again, sorry.

Ah-Ha, so you're the bandit Peter! We seem to have similar interests in watches

I've actually decided on a couple of Hamilton's that I want to add to my collection and the 4992B is one of them. I'll keep looking for the next one.

You mentioned that you've lost a couple that were marked US Govt. Do you remember what they sold for? This will help me understand the current market pricing.

-Steve

I had not researched the 4992B for the marking US Govt ....

Do y'all have a serial number range where they are not marked?

I have info on 992B movements so marked...

Terry,

I don't have 4992B serial numbers for movements that are not marked.

If you have serial number info on 992B movements with US govt markings, could you please post the info. Are there different markings besides US Govt?

When you collected the information on 992B's, what additional information did you collect besides the markings and serial number?

Thanks,
-Steve

markings i have seen are US Army and US Govt

The US Army are early.... and seemingly scarce...lowest serial number C4849.. highest C10832 .. they seem to be spread out in production..

i have 8 examples recorded in this range.

The US GOVT marking is more common, and there are examples beginning at C40073 with C114112 being the highest..

they are not concentrated in a certain range, but a decent spread thru the serial number ranges... there is not enough info to determine definite serial number blocks.... i have listed 55 examples so far with more to add.

i have been recording what type of case they are in .... MANY HAVE BEEN RECASED IN NON MILITARY CASES ......... and the type of dial.... MANY HAVE HAD THE DIAL CHANGED......

(caps for emphasis)....

Steve.... again my apologies. I wasn't aware that you were discussing it until after I grabbed it.

I don't remember how much others went for but... I seem to recall that the one I bid on went for well over $400.00 and there was "something" wrong about it.... case???

Peter, there's nothing to apologize for. These things happen and at least it went to someone I know It looks like it's a nice watch for your collection.

I've seen some 4992B's with a white 12 hr dial, seconds numbering, and a sweep second hand.
This one in particular has the U.S. Govt marking on the movement.

Were the 12-hr dials ever used by the gov't or would this have been converted for civilian use?

In the past I have seen a 4992B 'conversion kit' to allow a 24-hr movement to be converted to a 12-hr movement.

-Steve

What is the approximate price premium that the "U.S. Govt" marking adds to the 4992B?

-Steve

Here are some pictures of the 4992B I recently purchased. This is my first post as I just joined your chapter yesterday. I would appreciate any comments you may have regarding this watch. It's serial number is 4C19646 and is marked U S Government. I purchased The watch from Larry Jones http://www.larjones.com/data/pwgnrl.htm. He has some nice watches and is good to deal with. The watch is keeping perfect time.

Bob,

That is indeed a very nice looking 4992B! Like Lindell said in an earlier post, these watches are special to many of us for the reasons he mentioned...real pieces of American history on several different levels.

I've been reading all the old threads on the 4992B for a couple of months now to educate myself before buying my first example. Being "into" Hamiltons as well as military history and timepieces, I find these watches particularly interesting.
