Depends on your preference on the metal, you can choose from 5270J (quite classy actually if you like yellow gold), 5270/1R with bracelet or 5270P (great salmon dial and the prestigious platinum). Your relationship with AD will be elevated to another level after this purchase.
But from a collectibility or purist's perspective, 5970 or 3970 (if you accept its smaller size) may be a more popular choice, but you need to source a good specimen in the market.
Please keep us updated on your quest.
Best, Henry
