The "Bulova 23" and its workhorse movements the 10BPAC and 10BOAC

Hello all,

I thought I'd share my favorite Bulova model and the examples of these in my Bulova collection. If any of you have additional models (or similar for that matter) feel free to add pics to the thread for the enjoyment of all.

I've included a group picture as well as detail pics of each watch. All but one have original dials. Three (including the one with the metal bracelet) have original or NOS Bulova bands. All but one have Bulova marked buckles. I try to complete the "package" as much as posible when I can. But must confes that for my personal use I concentrate more on whether the band or buckle is hallmarked, than if they are correct to the period.

I've also included an interesting note from a technical publication referring to these movements.

I hope you all enjoy looking at them as much as I do owning and wearing them.

The 23 Jewel auto was Bulova's first US made Automatic. - 1954.

Mr. Fifth, you may be wrong. Didn't the Duo Wind automatics come out as early as 1951?

1950  - the 'DUO -WIND's were the first Bulova automatics to enter the US market but were of Swiss manufacture (Felsa movements).

The Bulova 23 was the first automatic manufactured entirely in the United States.

Hope this helps.

One interesting details about these is that one of mine with a stainless steel case similar to yours is marked "Swiss" on the inside of the case back, but the movement is marked "USA". I don't think the case backs for the RGP cases of the same style are marked "Swiss".

Duo Winds were Swiss movts. This may be one of the rarer cases of Bulova using an in house movt, or at least one made in the US. The BPAC is a dervative of the calibre BOAC, and shows no import codes, hence, I suspect it to be of US origin. It could also be that the casebacks reflect either the fact that the case is Swiss Made, or possibly that these were marked prior and when the US made movts were used, they used up the stock. My own thought is the latter, and that the cases are US also, but are stamped Swiss from a previous run to indicate a Swiss movt, which satisfies the Swiss made criteria, which was a certain percentage of the finished product produced in Switzerland, even though in this case, it doesn't. If that makes any sense.

The marking meaning that the case is Swiss made make sense to me. I'll look again and see what else is included in the case markings.
