Watch Description

This is an odd one. It's not a Bulova case, Its actually marked Providence Watch Case Swiss, probably some kind of jeweler creation or a recase, but that's not my main point of concern. I'm more intrigued by the movement. Its dirty, i know, i was going to wait to post until i had it cleaned up and more clear photos, but I'm getting anxious to hear what everyone has to say. I listed as 1925, but i am not so sure. 1925 10A should be free of serial numbers and date coded with an 'O" but this movement has a serial number and i cannot find a date code. i can find something that looks like it might could be an 'O' but really could just as easily be a scratch or imperfection. Also, the general geometry, the bridges and such, do not match that of the other 10A movements we have in the DB. The engraving font and placement are all different as well. The caliber stamping of 10A is a little off, the A looks more like an upside-down V, it's just all very inconsistent and appears to be an older style of markings that the 10A's I usually see.  Take a look and tell me what you think

Even though it is not a Bulova case, i still love it. Large with a 21mm lug width. strange for that time period.

There was a comment about there being no evidence that this dial had ever been in another watch case. So i decided to get up close with the dial and in the video linked below you can pretty plainly see one defined patina line around the entire edge of the dial. I agree, i see no signs that this dial had been in two different cases. ... Also, to add another aspect, i found a logo enbossed on the back side of the dial. It can be seen at the end of this video. Does anyone recognize that logo, likely a dial manufacturers logo? Perhaps it could help to know who made the dial and what years they were making dials for Bulova.

This logo found on the back and in the corner of the dial on subject watch. Shown in two orientations. Any thoughts on Identification?

This one is certainly a mystery. I am inclined to label this one as Unknown, as there really isn't enough info available to determine if it's "genuine Bulova" or not.

1925 Unknown (for now)

By the way, I Love the casing

Is this not the same style 10A movement as the subject? So why can it not be from 1925?

Regardless of the date, this watch I believe is a non-original Buylova product and as such should be entered as Non-conforming.

Yes, i agree. They are of same design and i would certainly be able to accept 1925, that was my first go-to, but the style of font and location of lettering is so different and seems earlier. Perhaps, this difference marks a period of transition, from one style to the next. Noticing the serial numbers of my subject watch, and that of the comp, they are only off by about 8,500.

Another 1925 example. Fifth I'm not sure why you think this movement has to be earlier than 1925.

Stephen,

as mentioned, the Bulova Watch Co hallmark is a more primative design than what is seen in 1925 and I am not so sure We are seeing an 'A',  to Me it looks more like an inverted Y or V.  In either case is does not match the A of the known 1925 10A moements.

Under the balance there is likely a trapezoid or triangle with a number. Can you check and let me know? Thanks!

I am not sure how to post a picture of it here without it having a url link, but it is very clear to see a Trapezoid with the number 42 inside of it. Took me awhile to find it, but once i did it became pretty clear what i was looking at. It very small and tucked away well under the balance. I have done it before, but i am not confident enough in my skills to remove the balance without harming it so i am not going to try and my watchmaker is out of town for another week.
