Please, help with Hamilton 4992B with 12 hour dial.

Real dial or is it a post-war remake for collectors?
I have not found such a dial any available books or on the Internet.

This topic has been discussed MANY times before. Here is a link to a prior discussion topic with more details:

Prior Topic on 4992B 12-Hour Conversion

Briefly, the 4992B's were originally made with black 24-hour dials and white hands. This watch is a postwar 12-hour conversion with refinished hands and dial.

I´ve seen "U.S. Gov't" engraved on the movements, but I´ve never seen it engraved with U.S. Army Air Corps, and that AIRCORPS without a space!

Here a 3992B marked U.S. GOVT.



My WWW collection is now complete, time to look for new ventures!

Aleksandr,
From the little I know of these watches Hamilton was supposed to have made some for the military with the 12 hr dial. I have a link to one identical to yours but cannot copy it to the forms. Send me an email and I will send you the link.

Edward,

The watches Hamilton made for the military during WW2 with 12-hour dials were the 2974B, the military 992B, and the 3992B, but NOT the 4992B. Those were all originally made as 24-hour dial watches.

The 12-hour 4992B's you encounter today are all aftermarket conversions of one kind or another, that's why you can't find them in the watch books.


Best Regards,

Ed

It's a fake dial. The U.S. Army Air Force was created on June 20, 1941 with the U.S. Army Air Corps as a subordinant unit, then the residual Army Air Corps was abolished as an organizational unit on March 9, 1942. The serial number on the back of your watch is 1943.

Writing numbers on this dial for this watch is very similar to the dial for watch 3992B.

It is in remarkably excellent condition. The lack of a serial number or an order number indicates that it was never sold to the military or used by them. Perhaps it is one that was assembled from unused parts sometime after the war ended?

Sorry, but I have no information about this watch. This pictures from Skinner auction.

Sometimes one can find "New Old Stock" parts of watches and assemble them into a working watch. I do not know if that is what this may be in part or in whole, but it is another possibility given the lack of the serial and order numbers

This particular watch is curious in the fact that we do not see ADJ TEMP. AND 6 POS. UNDER THE CENTER SECONDS BRIDGE as we do on other early examples of the 4992B's
Additionally I would expect to see U.S. NAVY BU. SHIPS,with a BROAD ARROW and or U.S.GOVT. in BLOCK FONT on a 3992B
I will therefor say that it is as Jim postulated To be "assembled from unused parts sometime after the war ended?"
Just my 2 cents

When I worked at Waltham Precision Instrument Co. there were a lot of people left over from the watch factory. On their breaks and at lunch time, they were always playing around, and putting watches together. They had boxes full of old Waltham Watch parts.
