Durrant hit a 107 average and six 180's in victory as he showed some of the form which saw him reach the semi-finals last year and he has set the benchmark ahead of facing either World Champion, Peter Wright or the in-form Portuguese debutant, Jose de Sousa next up.
Durrant lead early doors after both exchanged holds with the former claiming a break of throw and a 14-darter followed by a hold to make it 3-1.
At the break, he raced clear at 4-1 up with a 98.7 average and 50% on the doubles. He missed three darts at doubles though and De Zwaan found a break of throw with an 80 checkout to make it 4-2.
They traded 180's before Durrant claimed a break back straight away with an 11-darter to make it 5-2 to race clear again.
De Zwaan closed the gap to 6-3 but Durrant once again maintained his advantage as he looked to surge towards the second round with a 106 average to boot. He broke to make it 8-3 and a fifth 180 and double eight saw him go one away. From there, he concluded it 10-3 to finish an astonishing display.
