Watch Description

First, thanks to all involved for this fantastic resource!

Second, this looks like a Calendial D but a blue-grey dial variant (dial may be sun-faded). The "plunger' date quick change is a fantastic feature!

Third, Like neetstuf-4-u's, the inside of case back is ink stamped "3335" (https://mybulova.com/watches/1973-calendial-d-9028) with the same hour markers and "Automatic" within a white multi-line stripe.

Fourth, did Bulova change model names with different colour dials?

Fifth, would love to find an advert for this or any colour variations.

Sixth, what (if anything) does the small hallmark of "64" on the movement denote?

Finally, the (cheap and ugly) strap it arrived with will be replaced in short order.

Thanks and regards,

-G

Do you have a photo of the 64 stamp on the movement? I can see a N4 which equates to 1974

You can see it just above the balance wheel in the last photo. I'm not sure of the significance but I've see it on a number of the11AOACB movements I've worked on. I've also seen a '65' on an 11ANACB.

Thanks for the input and apologies about the photo. Was shooting with a phone through a loupe for detail.

Very nice watch. I love the "chunky 70's" style. Yours is indeed a Calendial, there were several variations of this one based on dial color. Yours is a 

1973 Calendial "E"

Thanks for sharing it with us!

Awesome, thanks for finding the line book!

Great to see it listed as a "blue degrade dial" with an "E" model variant. Interesting it had the expandable bracelet.

The 70s watches (of all stripes) offer some fun case variations.

With the line book prices, is the lower the wholesale and the higher the mrsp?

1973 Bulova Calendial "E" is a good match and a first for our database.  I wonder if the line book has an error by listing it as white but then describes it as gold plated.   Nice to see this variant in the full color metal

Good spot. The watch is yellow gold plated but harder to see due to rub off and the small photo.
