A very good quality movement, one of the US made ones, Heat, Cold and Isochronism, with three positions is only two positions short of a modern certified COSC Chronometer. (At the time, the standard was by the Bureau Officiels de la marche des montres, (B.O.'s) and was a four position, heat, cold and isochronism test with a delta of 11 seconds (-1 to +10) This became five positions in 1961.) To put this in perspective, only 3% of modern Swiss production today receives Chronometer certification.
Having said all that, I know I will get some flack for this if I don't mention that simply stating the watch is timed with the above parameters in mind does not a chronometer make it, (The critical measurement would be if it remained within the deviation allowed) but my point is that this is a very good quality watch.
I like 23's, and this looks like an S to me.
Yes I agree with the "S" variant call, right down to the inside case back info now posted. It even matches the 10K rolled gold plate text from the ad.
Based on the ads it looks like the 1958 "s" then. The ad on the 1956 has a slightly different dial. On the other hand, there is a L6 sign on both case-back and movement.
Hello Forester, welcome to myBulova. This is a fine looking watch, I've always been a fan of the 50's Bulova 23's. For me, these are some of the most iconic Bulovas.
I agree with the group that it's a Bulova 23 S variant. Thanks for sharing it.
Thanks for all the warm welcomes and time you guys put in this forum.
Got this one from Ebay, spending more money on shipping and import duties than on the watch itself. This is my first Bulova.
I really like this watch, so I'm sure this won't be my last Bulova.
I have collected Frensh watches for some time now, most Yema and Lip.
Most watches I own (and look for) are from around the 70's, 1 rule for me is No Batteries..

Nice to know there's another budding Bulova collector prowling the halls of eBay! Competition is good for watch collecting.
The great thing about Bulova collecting, other than the amazing variety of style over most of the last 100 years is our ability to determine the dates and model names. Stephen (admin) has done an amazing job here at myBulova rebuilding the history of the brand, the value to the Bulova collector is immeasurable. I look forward to your next 'find'.
Hello all. Would anyone know the part number for the crown on this watch? Thanks as always watch family.
In reply to Hello all. Would anyone know… by zappatore88
What's the case number of your watch Anthony?
Hello Geoff,
its C442210 - L7
thanks .
Hard to know which crown is the correct one for this somewhat hidden type, but here are a few site docs that list 10BPAC crowns.
It looks like #123 crown is a correct type.



Inside case number referencing didn't come into use until the early 60s.
