Edit: I installed kteatime so the problem is solved

I can see you already solved the issue (by using kteatime), but in case you (or anyone else) is interested, you can change the default timers in the event calendar widget by editing the defaultTimers variable array in:
$HOME/.local/share/plasma/plasmoids/org.kde.plasma.eventcalendar/contents/ui/TimerView.qml
It has 8 timer slots (you'll have to replace one of them with your own timer, if you have more than 8, the last ones are not shown):

label: i18n("75m"),
seconds: 75 * 60,

Once you're done, you need to restart plasma to have the changes recognized in the widget
