It was the slimmest automatic, and the original movement in the original 1972 AP RO.
I did have the option of the 15202 and 15300, but chose the 15300 as i just preferred the seconds hand, and the more robust movement, it's also not cheaper to service, as AP charge the same rates for both movements for their Periodic A servicing. The flagship movement for AP is the Grande Complications one, which i believe is manufactured by Renaud et Papi, the specialist movement manufacturers that AP own.
