Bob,

A very sweet Movement, the Hands are typical of 'Railroad Approved' timepieces of the era and possibly a requirement to become so? .

I may add that a luminous version of these Hands are found on the Military issue 3818A of the same era.

Star Case - 15 Jewel 10 BNCH.

Hey, those are  pretty sweet and great condition, but C'mon Mark, you've just snagged 2 of them. Rarity is determined by production numbers and we don't have that info. I'd say rarer or uncommon maybe but I think I hear sock drawers opening again.

These are the first examples of this Watch I've seen or heard of in over a Decade of collecting Shawn.  Try finding any information,....or parts!  Does anyone know what to call the doo dad on the balance cock?  2 examples in Hand, both are missing this part, only a piece of it remains.

Jay,

Thanks.

Note on the Movement in My example: there is a piece of the micro regulator missing, a large piece, the tip is left wedged under the regulator (arm?).

Both examples I have are identical this way, a weak spot or?

By design would be my guess. Chances are its some sort of stopper  to ensure the regulator isn't bumped or moved out of place. The timing and maintenance of railway pieces were strictly controlled from what I've heard.

Just because you haven't seen them, does not make them "rare", only production #'s can make that call and we don't have those. So the claim to be rare is meaningless without any data to substantiate it. I've recently been called on calling a Hamilton Electric "Railroad Special" as a "rarer" watch, not rare just "rarer "as I believe all the Electrics are due to limited production from 1959 to 1963. Seems like the sock drawers opened up and all of a sudden 5 more were listed on Ebay . You may have your opininions, but that's all they are, speculation on your part. Wait for the sock drawers to open up on these Bulova's and you'll see more of them, especially if they sell for big money. I initially gave 3 stars on the ID, but now it's 2. You need an ad to substantiate that ID as without that you have no provinonce to the ID since one is stainless and the other RGP cases.

Rare, I think not,  a dial print does not make a model ID. The Hamilton "Railroad Special" is noted as the RR50 model, not "Railroad Special" as marked on the dial. IMO 2 stars.

Bulova never printed letter designations on the Excellncy line,  and in fact they only printed "Excellency" If even that on several models in the 'Excellency" line so the print on the dial means nothing,  IMO.

What does the R at the end of 10BNCHR stand for?  Dr Rantfff only lists the following:

Bulova had a pretty straight designation system:
a number representing the rounded down width in lignes,
first letter: distinguishes between calibres of same size used in parallel,
second letter: generation of a particular calibre,
further letters:
A: automatic
B: day/date
C: sweep second
D: date only
L: no second (often used for blind men watches)
