Rollei 35 S or SE. No rangefinder, so it is guess-focus (scale focus), but you have a full range of aperture and shutter settings.
The Minox GT-E is also very good, lighter than the Rollei, but only has aperture control. Shutter is automatic. In other words, it is aperture priority AE. It is also a guess-focus camera, as there is no rangefinder.
Ah, but you have already ruled out the two most pocketable cameras above.
Leica IIIf with collapsible lens. Heavy, bigger than either of the other two. Fits in a coat pocket. Has parallax corrected rangefinder focus. Put a Voightlander VC II meter on it if you want a meter.
+1 Leica IIIf. Lens is magnificent.
