Nineteen of the Russian's 21 championships have been earned on hard surfaces
A comeback Medvedev secured his first championship for nearly 30 months with a win over Frenchman Moutet in the competition championship match.
Medvedev, a former world number one, has endured a difficult period, achieving just a single victory at the Grand Slams and undergoing a meltdown at the American major.
His unpredictability on the tennis tour - and issues with his serving in specific - led to him dropping out of the top ten and ultimately splitting with former trainer Cervara.
Presently working with his coach and Rohan Goetzke, Medvedev has gradually improved in the recent weeks - peaking in a closely contested competitive win over challenger Moutet.
This marks his first trophy since the Italian tournament and maiden on a hard court since spring of that year.
Success also indicates the Russian has won twenty-one victories at 21 distinct competitions.
"For the first time I'm at a competition with my children simultaneously, so to get a trophy is particularly special," stated ranked player Daniil Medvedev.
"This title is in tribute of my second daughter my daughter, because the maiden victory I achieved when my older daughter my daughter was born was for her."
The athlete, the past champion, had lost his past six championship matches, comprising in Halle in the past months.
Medvedev's defensive strategy and recurring reactions on the tennis court had prompted commentators to question if his ability to play at the elite level was finished.
Yet the 29-year-old has implemented adjustments in recent weeks, making an effort to advance forward and compete assertively, supported by an enhanced serving game.
He came back from a disadvantage in the first set against the challenging Frenchman, winning 4 of the last five games to go ahead.
Both players exchanged breaks in the second set before the challenger, striving for his maiden tour victory, took control to force a third set.
Moutet saved 4 early break points in a tight third set before the Russian broke to fifteen to serve for the match.
Suitably, he clinched the title with a rally at the net, with his opponent incapable to manage a shot after a lengthy match.
