Nineteen of Daniil Medvedev's twenty-one victories have been earned on hard surfaces
A resurgent the Russian player claimed his initial trophy for over two years with victory over Frenchman Moutet in the competition final.
The Russian, a former world number one, has experienced a torrid year, achieving just a single victory at the Grand Slams and suffering a setback at the US Open.
The player's unpredictability on the ATP Tour - and difficulties with his serve in especial - caused him dropping out of the top ten and eventually parting ways with long-term trainer his previous coach.
Currently collaborating with Thomas Johansson and Goetzke, the tennis star has steadily progressed in the last few weeks - culminating in a closely contested three-set win over opponent Moutet.
This represents Medvedev's initial title since the 2023 Rome Masters and initial on a hardcourt from that period of 2023.
The win also means the Russian has secured 21 titles at 21 different tournaments.
"It's the first time I have attended a event with my children simultaneously, so to get a title is particularly special," commented tennis professional the champion.
"This title is in tribute of my second daughter her name, because the maiden victory I achieved when my older daughter her name was born was for her."
Medvedev, the 2021 US Open champion, had failed in his last six title deciders, comprising in Halle previously this season.
Medvedev's counter-punching play style and regular reactions on court had prompted observers to question if his skill to compete at the highest level was concluded.
However the 29-year-old has altered his approach in the past month, making an effort to come to the net and perform assertively, supported by an enhanced serving game.
He fought back from a break down in the opening set against the challenging opponent, taking 4 of the concluding five exchanges to take the lead.
The pair traded breaks in the following set before Moutet, striving for his first ATP Tour victory, took control to create a final set.
Moutet saved four initial opportunities in a tight deciding set before Medvedev broke to 15 to secure the win.
Appropriately, Medvedev clinched victory with a rally at the net area, with the Frenchman incapable to manage a return after over two and a half hours.
