Additional Information: 

Found this last week at a thrift store, hence know nothing about its history.

Movement:  10COAC, 30 jewel

Movement Date Code:  M9 - 1969

Case Date Code:  N4 - 1974

Unfortunately my camera is not sophisticated enough to capture these date codes, sorry.

On 26 February 2015 ChefBenjamin posted a watch cosmetically identical to mine:

http://www.mybulova.com/watches/1973-unknown-7246

I would be willing to wager that his watch is mechanically identical too.  But it went unresolved as to whether his watch was an authentic Commander because he could not post a photo of the movement.

My watch does has a 30 jewel 10 COAC movement as did all of the Commanders.  My watch also has a Commander AQ gold plated case.  The only difference between my watch and the 1960s Commanders is the dial and hands, updated to a more current 1970s style.  And my dial does not say 30 Jewels.

Is my watch authentic Commander?

hello jshopper1, welcome to myBulova. Like ChefBenjamin's watch, which seems to be the same, yours is difficult to correctly identify. My concern with a commander ID is based on the dial, which is not the same as the advert and the 5 year difference between the movement date code and the case date code. When we find something more that a year difference we suspect a replacement movement. Typically 30 jewel watches by Bulova were noted as such on the dial and yours isn't. These factors make me think your watch is a combination of at least two models. Generally we note these as Non-Conforming, which means they don't represent a single Bulova model. It is still a fine looking watch and should be proudly worn! Thanks for sharing it.

Geoff,

Thank you for your kind input.  I learned much from it.

In your review above you said:  "These factors make me think your watch is a combination of at least two models."  Can you specify which two models?  Anybody?  One could be the Commander.  Which other models do you have in mind?  By the way, I am not arguing or contradicting what you said.  I just have a curious mind and want to learn.  I searched long and hard looking for other 1970s Bulova models with similar dials because I thought the same thing also.  Came up empty, other than ChefBenjamin's.

Maybe they are out there and I just didn't find them.  Anyway I suppose that Non-Conforming is a step above Unknown.

Anyway thanks again for your assistance.

I'm suggesting that the movement doesn't belong to the case and dial. I'm not sure the dial doesn't belong with the case, it is quite likely that is does. Bulova generally put 30 Jewel on the dial but if someone added a 30 J movement to a non 30 dialed watch it could be Non-conforming. If someone put a 1969 movement into a 1974 case we would consider it Non-Conforming.

Geoff,

Thank you again for your kind response.  I understand your comments and agree with Non-Conforming.

When Bulova fabricated this watch in 1974 using a Commander AQ case they had to use a 10.5 ligne movment because the Commanders used a 10 series movement sized at 10.5 ligne (unless they used a smaller movement and a spacer ring, but why would they).  As I understand it, the 10COAC movement was the end of the 10 series line and the most recent.  Therefore most likely the available movement parts in inventory were 10COAC parts (with 1960s date stamps).  Hence I think that the 10COAC movement was most likely correct for this watch.  What else did Bulova have at the time to put in it?

The above is just my opinion and cannot be proven until some factory advertising verifies it or lots of examples turn up.  I also believe that since two of these examples exist, there could be more out there waiting to be found.

Again, just my opinions and certainly not proof.  I do appreciate your knowledge and thank you again for your time.

jshopper1 - is there a number stamped on the inside of the caseback, typically four digits sometimes with or w/o a letter? This number can be referenced with a parts book to determine the movement associated with this case (assuming the case and caseback are original to one another). Thanks, Ken

The lack of '30 jewels' on the dial is not unprecedented, Lisa has a couple from the early 70's, but not Commanders. These were unsteady times, and companies were starting to struggle. The quartz crisis was just getting started, and prices were beginning to drop as the cheaper movements were being used. 

I'm not sure what to make of the 5 year spread on the movement and case, usually this indicates a swap, and we do think that the 10COAC ended in 1969. If Bulova were to update the Commander, they could easily have them made the cases (or spacers) for the newer 11 ligne movts, so why use an old movement? There is actually only a small difference bewteen the 10 1/2 and the 11 ligne movts, and it would be simple to use either with the plastic spacer rings at the time. A french ligne is  2.2558291 mm and the difference between the two sizes is less than this. 

What would be nice of course would be some early seventies ads showing the Commander, but that still wouldn't give us any info on the movt, especially if they dropped the '30 jewels' from the dial. I don't know why they would do this, but they did do it on another model, it is listed as unknown on Lisa's site.

Ken and Rev Rob,

Thank you for your comments.

Ken, the watch is with my watchmaker getting a COA and new crystal, so I do not have it in hand.  I don't recall any marks on the inside case back, but I also have trouble recalling what I had for lunch yesterday.  I will try to get the info requested from him, if not it may be a couple of weeks until he sends it back.  I will post back when I get the info.  Thanks for comments.

Reverend Rob, interesting insight.  I doubt that my watch was part of a large production run.  Hence I doubt that we will ever see an advertisement.  They may have been a clean up run of old inventory or they may have been a special run dedicated to an single private buyer, possibly to be used as a sales incentive (i.e., buy a time share condo and get a free watch).  Or maybe some other yet to be discovered reason.

As time goes by I hope more will come out of the woodwork so we can figure out what is correct.  Don't you love a good mystery?

Thanks again everybody.
