Took a gamble:

Caseback is known to be stamped on the outside - B-10K Rolled Gold Plate
0273122

Unknown if the inner Caseback is stamped - 17 Jewel Movement (center Seconds 10''' ?) Dial looks original and authentic.
and for Your pleasure http://home.mchsi.com/~partymixdj/audio/ramblin.mp3
Any thoughts? other than it needs Hands.
The dial has some things in common with the 1938 Buckingham and the 1942 Practitioner--most notably, the absence of the sub-seconds dial.


.....and the Calibration of the register / track.

Tickers 1940 'PRACTITIONER' - Good eye Lisa, We need to drop the 'novice' from Your screen name.
In reply to .....and the Calibration of by FifthAvenueRes…
Ha! You flatter me.

Feel flattered all you like, but Im in agreement..drop the novice as you are far fom it.
I wonder if this Case is legit?
We shall see....
The signature on the back looks good. Lots of us have quite a few watches with that signature only. May be a test of whether you can "believe" in this one.
You may have a point.
The Case would seem to be era correct if not exact (based on the seriel number), so I doubt it's a later replacement.
The watch being discussed appears to be a REGULATOR, per the 1st 1941 add in the ad data set! I have been looking for one for some time . The lugs are add ons to the case on the Practitioner and Buckingham. The lugs on your example are a part of the bezel/case. In addition the case has a step on each side , like the Regulator. There is a discussion of the Medical Officer and Regulator in this thread:
http://www.mybulova.com/watches/1941-medical-officer-845
A regulator was also a precision clock maintained at designated RR Stations or jewelry stores for use in scheduling trains before the US established time zones. Reason, every town kept its own time putting trains on the same track in danger of colliding, since there were not many tracks and sidings. So the various RR lines got together and desinated Regulator Clock sites, started publishing schedules, engineers and conductors made certain their watches good for the area where the train was operating . Eventually the telegraph was added to regulator clocks and saftey improved, and you can imagine the rest.
In reply to The watch being discussed by JCEagle
This is not The Medical Officer or The Regulator. Check the shape of the crystal. It has a distinctly Bulova look to it and I'm hoping that it's something that we haven't seen yet.
Jay
I'd have to agree Jay.
The steps on the side of the Case and squared off look are all Bulova.
I hope the Caseback is signed....I'm betting it is.
You are right, got excited and didn't pay attention to the picture only my reference list for the ads! :<]
Looks like the dial is way off center... optical dilusion???? Looks cool, hope its legit..
Camera angle possibly Shooter. We'll know in a few Days.
I hadn't paid much attention to JC's post on the 'MEDICAL OFFICER' but the Bezel has definate similarities.

Things are looking up for the 'UNKNOWN'
I look forward to helping investigate this watch more......when we have all the facts.

Paydirt.
: )
Very cool. Was the apparent problem with the dial fit simply a matter of camera angle?
Looks small like a ladies, what is the movement series??
Ticker,
17 Jewel 10 AE. - The Watch is too large to be a Ladies model.
Lisa,
I dunno I ripped it apart as soon as it arrived and didn't pay attention. I will clean it up a little and add it to the database.
Paydirt?? Now we're looking for another model ID in the Bulova can of worms. Well done Mark.
BTW, I do really like the watch too. Nice find! Oh Yes, Please do post it with all the relevant info so we can start hunting. Slick watch deserves a name.
That looks like a pretty heavy case, not thin and flimsy like most.
Happy its real !!!!!!! Great gamble Fifth !!!
