1957 Bulova Senator “H”
SN C631857 on a Stainless Steel case back
L7 date code
17 jewel 11AC movement with L7 date code
1956 ad in the pictures
crystal measures 23.1mm x 18.7mm
The crystal is square when viewed from above.
It is domed crosswise as well as top to bottom.
The underside of the crystal is arched on all sides.
The case does not allow for a crystal that is flat under any side.
While the illustration in the 1956 ad is poor, it’s sufficient for identification by comparison.

I use an impregnated cotton wadding called "NEVR-DULL". It works wonders on watch cases and is reasonable cost and a can literally lasts for years. Tear off a wad and buff watch then polish with a soft cloth. It doesn't remove plating or scratches, but does wonders for overall appearance.
It's available at some hardware stores; I get it off eBay. Just type NEVR-DULL into search.

Dude... every pretty watch I put up has been cleaned/polished with these cloths.

Just use the ones for Gold... the white side of the cloth cleans and polishes, the pink side shines them up fierce.
