Gabriel Martinelli put the Gunners in front, capitalising on an electric start with a smart header on 20 minutes.
New signings Gabriel Jesus and Oleksandr Zinchenko thrilled an exciting Arsenal side in the first half, backing up their perfect pre-season record.
But manager Mikel Arteta was made to sweat as the hosts came back into the game and dominated the second half.
An Eagles equaliser looked more likely in the closing moments but the visitors doubled their lead as Marc Guehi inadvertently turned a Bukayo Saka cross into his own goal.
