1956 Bulova 23 'H'
10KT yellow RGP case, stainless caseback dated L6. 23 Jewel 10BPAC movement, self-winding and dated L5. White sunburst dial with golden hands and markers. Not sure if the JB Champion gold band is original, has a nice look with the case.
Supporting 1957 Ad and existing model in the database
I'm seeing the 31315W number in the ad as the white model variant "F". ...but I'm also seeing that the price of the "F" is $85. The price lists show the 31311 Y as the "H" variant about this time- price $95 as in the ad used. Maybe the ad pictures the yellow "H" and use the price of the "H" in the ad, while using text of the 31315W for description. So $95 is for "H" and $85 is for the white "F". The price in the ad looks to be typed in.

I think both the "H" and "F" morph into a two letter variant by 1958, but still have the same unique 31311 and 31315 model numbers, respectively.....and of course, we have Geoff's linked H example with a 31311 Hangtag.
