Option 1 -1931, IMHO because the idea, the prototype would be ready by then...may even be production

Patent merely protects the rightful ownership of the idea - nothing more !
and the reverso from first production...in JLC Museum!
and the very first Limited Edition of Reverso in 1949 from the museum...Steel case, Yellow Gold case back with Grand Feu enamel and a caliber 410 inside !
Best,
