because your watch has a black dial is a Midnight Clipper like here
I was scrolling throug the 57's and came across another one. Beautiful watch. A keeper
Nice Midnight Clipper. The black and gold is always a striking look.
I wish I had a dial like it for my 52, much larger 34.25mm case approx 29.5 dial. Just can't find one at a reasonable price.
It says 17 Jewel , does that includ the jewels in the rotor or does that really make it a 23 ?
If it is engraved 17, then 17 is the total jewel count, including any jewels in the automatic module. At one point, during the so-called 'jewel wars', manufacturers would place non-functional jewels in the watch movt to up the count. These sometimes would simply be jewels under the dial that served absolutely no purpose, or would have a marginal function, like being the surface the date disc revolved on. The dials had ludicrous jewel counts sometimes up to 100. This was stopped in the 60's.

1957 Bulova Midnight Clipper works for me.
