    Bulova pocket watch movements.

    Does anyone have any info on these movements?
    One guy says that these are Bulova-made movements, made in their Swiss factory in the early 1920's. I agree with the date as being pre-April 1923, but I wonder if they use some other manufacturer's ebauche? I can't find a match at all on Roland's site using the advanced setting, maybe someone has a match.
    (BTW, the triangle stamp in no.1's balance well is not a date mark!)
    Thanks, Bob.

    Number 1.
    Hairspring stud for no.1.




    Keyless works for no.1.








    Number 2.

    I'm sorry that you are't getting any replies. I wish I could help but alas, my resources are only as good as yours (or even worse.....). All I can say is that the positioning of the gears shows that it isn't two bridge versions of the same movement. The two are entirely independent of each other.

    Thank you.
    The lack of replies at least show that I am not the only one in the dark regarding these early Bulova movements.
    If there are any collectors of early Bulova wrist watches, I wrote a short blog on these, including a timeline and possible/probable identification of some early lines. I hope I have not broken any rules by linking to it. If so, please remove.

    Re: Bulova pocket watch movements.

    although "Bulova W.Co." rather than "Bulova Watch Co." name "likely" predates 1923, i do not think that can be 100% certain, possible exceptions may exist? The triangle mark for 1926 looks exactly that - 1926?

    not sure but the second watch may have a mark after the serial number.

    do the inside cases have and names in them?

    just my 2 cents.

    There is some talk that Bulova used some early Gruen movements?

    Hi Barry
    By Gruen, do we mean Aegler as the last poster implies from your link?
    Because that movement is surely not an Aegler or Rebberg movement.

    More like Fontainemellon?

    Don't think these had any connection to Aegler at all, haven't seen any reference for their 10-12 size pocket watch movements besides what they manufacture mostly for wristwatches in the 1900-1920s. Gruen SemiThin Movement 740 has most resemblance to the bottom 5 adjustment one. If you conjoined the fourth bridge to the center bridge for the Gruen 740 and shaved the bridge down a bit you could have almost a perfect match. Here is a Gruen 740:

    The Bulova Hi-Thin movements are certainly mysteries. I've came across a few throughout the years and have owned one several years ago. They might be the first pocket watch movements to be labeled Bulova so it pre-dates any dating nomenclature. To me they look like attempts to enter the market with standard quality ebauches and putting higher adjustments so that they will run good, especially for the American market. This looks to pre-date 1920s a bit and at that time American market was still mostly dominated by 16-18 size watches, whereas this is between 10-12 size. Here is an example I used to own:

    Re: Bulova pocket watch movements.

    OK
    As I said not Aegler.
    and I don't think Gruen either, sorry Ben.

    I mostly agree but we can't say for sure, especially the fact that during the time period there were hundreds of ebauche makers who did not label their movements due to customer demand. You could see if the Gruen 740 or any of their SemiThin models were altered a bit they could become something like the Bulova. Gruen had an impressive lineup of 10-12 size watches, they had the manufacturing capability but it doesn't mean they needed or wanted business from Bulova. However, they certainly did make the base caliber for other brands, especially their partner Alpina. So we can't rule anything out, but I'd say unlikely.
