I wonder if the poster could remove the dial and see if there is any info on the back of it and on the front of the movement. Some of my older watches have info stamped on front of movement and I seem to remember a dial having the crystal number or model number on the back side of it in a string I followed some time ago. It doesn't really look like there has been a bridge swap on the watch but you never know. I do recall a string mentioning the little flower in the center of the sides of the case on a particular unknown you were working with, but again, it was sometime ago. It also looks like, under higher magnification, that here might have been a date code on the barrel bridge on the upper left side between the two small screws but not sure. The closed nine is consistant with the period but the hands just don't match to me. Maybe it's just lack of experience rearing it's head up or something like that.

The Black Modern style Hands are correct with the raised Gilt formal (Dress) Dial of the period John, ads on site.

 

21 Jewel 10 AN - no Date code, no seriel number, no Country of origin. Case Dated 1931, Dial stamped Swiss..

OK....so Bulova did have 21J movements in 1931.....I've learned something today....cool. :-)

Sorry Mark, I edited my silly post of which I should have looked up a few things before making that statement about Bulova not having 21J movements that early. My bad.

The Conrad is a good starting point, or a variant of the Conrad. There weren't too many 21J at that time frame I think. So other than the enamalling Conrad is the closest we have at the moment. Not my ID but something to keep in mind.

1930 Bulova Conrad

1930's version used the lumed dial and hands...I wonder if the later 1931 also had a slight case change along with the update to the typical later hands and raised dial...possible but nothing the prove it...again just a thought and something to keep in mind.

I have the same watch, same hands and dial.  The serial number begins with a 0 and the movement is exactlty the same, 21 jewels and no date code.  The Conrad has engraving on the right and left of the dial, where the subject watch is engraved all the way around.

admin,

the Case design/style is incorrect for 1941

Didn't Plainsman have a watch with the little flower in the middle of the sides of the bezel? A discussion on ID involved that aspect of the watch and I don't remember if you ever made an ID on that one but it keeps popping up in my head. Sorry I didn't notice the raised numerals with the modern hands. The advert says radium dial so I didn't pay attention to the subjectt watch to see that it was not radium dialed. I have to look harder at what I see and maybe I won't make those kinds of errors.

Could this be a redial that the owner didn't want to pay the price for a relume on the dial and went with raised gilt as an alternative?? That might explain the hands.

Is is my eyes or are there burnish marks on the barrel bridge and train wheel bridge?? Don't know if that is significant or not but looks strange.

Unknown, but a neat looking unknown...The dial is similar to others that start out with lumed numbers in the late 20's and switch to applied numbers in the early 30's.

I'm in agreement with OT on this one. Unknown but a really nice one. The dial and hands look to be original as does the movement. I don't think the bridge has been changed and though I can't say for sure on this one I have seen date stamps on the lower plate between the bridges.

On a side note, I don't see any avenue to cast vote other than commenting.

Shawn there is no vote casting on the newer additions, only the older ones. Panel members put forth their model ID suggestion and if the majority of the panel agrees then I give the watch the correct model name and tick the 3 ticks. In this case it wouyod get no ticks as its a potentail unknown.

Unknown for me.
