Bulova 1942 Stop-Watch

There is a stop watch function

Medico, possibly?

The movement photo has complications which look like "more than a hack feature".  Jewels match ad, and it sure looks like the Medico.  Nice ad find again Bob.  Would Bulova had mentioned the hack/stop feature in the ad?  Not much said about the other watches featured above, but this complication may have warranted at least "stop watch" text under ad (if there was room).
 

Wouldn't this be a single button chrono? I'm not seeing the timer hand in Bob's Medico ad and I think the Medico just has the normal sweep seconds.

Medico has four hands, same as the one-button chrono.

I'm not saying it is this watch, but it seems to fill all the requirements apart from the crown, which cannot be seen at all anyway.

The ads were very tight, Will, with no room below as there was another row of watches by other makers.

EDIT:- What I meant to say was, The Medico could possibly be the one button chrono.

DOH! My mistake Bob. The Medico does have the timer hand as well as the subseconds.

yea DOH from me... I see the timer hand now too...just relied on the text and case shape etc...and not the timer hand and subseconds pictured.  The "sweep second hand" text through me off.

Medico works for me!
