If you could bump up the requirement to 41mm, the BB would make a nice addition. You would be spoilt for choices at 42mm ono but it all depends on whether your wrist could pull it off.
Pic : BB was amongst my fave wear some years back.

Pic : Same BB, newer colours after Basel.

Pic : Pelagos at 42mm, light and toolish.

Pic : PO was rather charming too- this was the 45.5mm.

I genuinely thought that the PO 37.5mm looked rather befitting on your wrist. You would want to wear the watch and not the other way round. I have had my share of getting humongous watches- only to flip them off after a while. But cest la vie, that's part and parcel of the charm being WIS
