Was this made in 1940?
What branches of service used it?
Can the serial number 19347 fix the exact date?
The Bulova 10BM was produced with 15, 17 & 21 Jewels.
Regards, P/L

Hi PL - see here for discussion on identical watch

Movement Serial No. 32991
Watch Serial No.2380650 US Defence ordinance No.7197108

Quotes:

The Ord. Corps. post-date 1950, which is when the Ordnance Department changed its name to the Ordnance Corps.​
If it is correct that the 1917-H was concurrent to the ORD. CORPS. watch, which is most likely correct, then a case date that matches the curved case serial number would be a good way to date this watch. 1952.​
It is thought by many experts that the 1917-H is a Naval watch, and the ORD. CORPS. is for the Air Force, both general issue watches. These watches are thought to be recased ORD. DEPT. watches, whose poor chrome plate more often than not had worn out.​
I believe the date on this watch should be changed to 1952. The 7198010 is not the case serial number but the US Dept of Defense ordinance order number which was issued in 1951 and was A7198010 as shown in the dial envelope documentation. The watch serial number is 2380650. I have the same watch with the same 7198010 but my serial number is 2389571 which is a spread of 8921 digits. It is possible up to 10K watches may have been produced.​

Hope it helps.

John, Thanks for the link.
The serial number of your watch is 32,991 and the ORD # is 7197108 not A7198010 of 1951.
The # 2380650 I think is likely the STAR case number, more to follow.
Regards, P/L

My watch movement is far too pristine to have served in a case long enough to wear out the case.

PL - I am no expert on these watches, but I don't believe you are interpreting the link I posted correctly, or at the very least differently from my interpretation.

I think there is a distinction between the serial numbers of the movements and the serial numbers of the watches, also the A7197108 number you quote is, I believe, the ordnance drawing number (Ord Dwg No.) for the ordnance number 7197108

So as you correctly say there is a significant difference in the movement serial numbers - #19347 & #32991

My understanding of the text on the Bulova watch site forum was the serial numbers on the case is being described as the watch serial number. This on the basis that this was a more accurate representation of the date of issue as some of these military examples had been re-cased prior to receiving the US 1917-H designation.

So comparing the markings on the inside of the case back (your watch on the left) ...

1634769688256.png 1634769770274.png

Your watch #2403079 compared with #2380650 with the same ordnance number #7197108.

So if both the Bulova's serial numbers and the Star Watch Case Company's serial numbers are chronological, my inference would be that you have an earlier movement but it was housed in an ordnance #7197108 case later. I have no idea whether lists exist for either to enable dates of manufacture to be determined.
