Nineteen of Daniil Medvedev's 21 titles have been achieved on hard surfaces
A resurgent the Russian player won his initial championship for over two years with victory over Frenchman Moutet in the competition title decider.
The athlete, a former top-ranked player, has experienced a difficult year, winning just a single victory at the Grand Slams and suffering a difficult moment at the New York tournament.
Medvedev's varied form on the professional circuit - and issues with his serving in particular - led to him dropping out of the world's top 10 and eventually separating with former trainer Cervara.
Currently working with Johansson and Goetzke, the tennis star has gradually progressed in the last few weeks - climaxing in a tightly fought competitive win over challenger Moutet.
This represents the player's maiden championship since the Rome competition and first on a hard court from that period of 2023.
Success also signifies Medvedev has won 21 championships at twenty-one different tournaments.
"It's the first time I am participating in a event with my children together, so to secure a championship is especially meaningful," stated world number 14 the champion.
"This championship is in dedication of my child Victoria, because the maiden victory I got when my child her name was born was for her."
The tennis star, the past champion, had lost his last six title deciders, comprising in Halle previously this season.
Medvedev's retrieving play style and frequent reactions on the playing surface had caused observers to question if his ability to play at the top level was finished.
But the 29-year-old has altered his approach in the last few weeks, striving to approach the net and perform assertively, backed up by an improved serve.
Medvedev came back from a deficit in the opening set against the challenging Moutet, taking four of the last five exchanges to go ahead.
Both players swapped break points in the middle set before the Frenchman, bidding for his maiden tour championship, took control to force a decider.
He saved 4 initial break points in a competitive third set before Medvedev won the break to 15 to close out the victory.
Fittingly, he secured the win with a shot at the net area, with Moutet unable to handle a volley after a lengthy match.
