Bulova movements made in USA. 

#1 Post by 441victor » Fri Feb 17, 2012 3:00 am

Bulova is most often considered an American company that imported movements from Switzerland and only cased and timed them here before selling them. Much like Benrus, Gruen and Whittenaur. Actually Bulova manufactured more different movements in the US than any other company except Elgin. I have been compiling a list of Bulova movements from photos or examples I have seen that are marked USA. With the exception of the 10AN grade which was produced in Switzerland starting in 1925 and was also made in the US starting in 1934, all of these grades were produced exclusively in US factories. The first year of production for most of the list came from the myBulova.com site. When not found there I used the oldest date from photos or my personal movements. Most interesting to me are the automatic movements (those with an A in the designation) which are not thought of a full blooded American movements because they are based on Swiss designs. I'm also starting to research the date movements (those with a D) the first of which is a pointer date movement, 10BMCD, that was the second to be made here in the US after the 1944 Waltham Chronodate. I have a partial movement that I am restoring. Other interesting moveme ts are the 10AKCSH (Center Second Hacking) and the 10BNCH which were issued by the military in A-11 and A-17 cases.   
Here is my entire list. I would appreciate any additions or corrections. 

10AN 1934 (first American production)
10AE 1935
7AK 1936
7AP 1937
7AH 1938
8AE 1939
10AX 1940
*10AH 1942 (one button chronometer)
10AK 1942
10AKCSH 1942
10BH 1948
7AA 1949
8AC 1949
10BM 1949
10BP 1950
10BZ 1950
10BZC ?
10BZAC 1950
*10BZACD ?
10BMCD 1951 (second American made pointer date movement after Waltham)
10BNCH 1951
10BMC 1953
10BPAC 1956
*10BPAD 1955
*10CBAC ?
10CBCD ? (first American made window date movement - *may have been preceded by the 10BZACD)
10COAC 23j 1961
*10COACD ?
10CPACD 23j ?
*10CRAC ?
10CRACD 30j 1966

I don't recall ever seeing what year Bulova's US factory stopped producing mechanical movements but I'm guessing in the 60s. I've seen a M1 (1961) marked 10BNCH military watch so perhaps it was during the period they were heavily invested in developing the Accutron that they finally switched to all Swiss movememts.  (*found a 10CRACD movement marked M6 so production continued at least until 1966)

*In honor of the resurrection of this thread, I did an edit to add more movements and intro dates that I've found since I posted this.

Joel -

Interesting information. I never knew that Bulova made so many movements in the U.S. Thanks for the education.

Joel,

An interesting thread and very educational. I only have a handful of Bulova's and I have one that is a bit of an anomaly (to be sure). I don't even remember where I got it, but it has a hideous refinished dial (see my "minty" post in the Hamilton forum), no sub-seconds dial and the movement is marked Swiss and BII - 3 adj. Not being an expert (not much more than novice) in these things I just thought I would show it.

Image

Image

This is an old favorite - I think ca 1959 - 23 jewels, self winding with a nice patina on the dial and a cool scalloped bezel.

Image

Image

I'll have a look at my others and see if there is anything that will help you.

Edit - one more - this one is rose or coral gold filled (not sure what year - 40's?) and the movement is marked 8AH and below that BXW (which appears to pertain to an import code for Swiss watches - link here http://www.mybulova.com/node/3953 ). Have never seen that before.

That's a 'Squadron', from 1946. See the little square on that raised area near the balance? That's a date mark. The square indicates the year within a particular decade, and in this case '6' in the 1940s.

A few years later, Bulova went with the letter/number code. They started with 'A' for the 1940s, but then 'L' for the 50s and continued serially through the alphabet.

I thought it was 1946, but in looking at the reference I saved there seemed to be numerous years where they used the same (or similar) square mark to denote the year code. Thanks for identifying it - Squadron is cooler than "rose gold thing with hooded lugs" :lol:

I also hang out at mybulova.com sometimes, so I'd seen that one before. For a while I considered also collecting Bulovas, but there's only so much time and money! I like their watches from the late 30s, like the American Clipper,

Image

And from the 40s, like yours or the Senator...

Image

And they also did some cool watches in the late 50s, like this 'His Excellency'...

FWIW, I have a 10BZ stamped USA dated to '65, (M5). I don't have a pic showing the date stamp otherwise I'd post it.
