During cruise at FL320 we got a brief Avionics Smoke indication that lasted approximately 3-5 seconds and extinguished. Following that indication approximately 2 minutes later the indication occurred a second time and remained indicated. We complied with the ECAM and QRH. Despite no visible smoke or smell we treated the indication as a valid indication and donned O2 masks and requested priority handling. We proceeded to ZZZ and landed on RWY XY. Fire trucks found no fire indication and we proceeded to taxi into [the gate]. Maintenance indicated after block in that the aircraft had suffered water intrusion days earlier and that they believed something in the avionics bay possibly shorted out causing the Avionics Smoke indication.
A300 Captain reported an AVIONICS SMOKE alert that lasted 2 minutes during cruise. The Captain requested priority handling to their destination airport.
