Nineteen of Daniil Medvedev's 21 victories have been achieved on hard courts
A comeback the Russian player secured his initial championship for nearly 30 months with success over Frenchman Moutet in the tournament final.
Medvedev, a ex- world number one, has had a difficult year, achieving just a single victory at the major tournaments and experiencing a setback at the US Open.
Medvedev's unpredictability on the professional circuit - and difficulties with his serving in particular - led to him dropping out of the world's top 10 and eventually separating with long-time coach Gilles Cervara.
Currently training with Johansson and Rohan Goetzke, he has gradually advanced in the past month - climaxing in a hard-fought competitive win over challenger Moutet.
This marks Medvedev's first trophy following the 2023 Rome Masters and maiden on a hard surface after spring of the previous year.
The win also means the Russian has secured 21 championships at 21 various events.
"It's the first time I have attended a competition with my children simultaneously, so to secure a title is really nice," commented world number 14 Daniil Medvedev.
"This championship is in honour of my second daughter her name, because the first title I achieved when my older daughter my daughter was born was for her."
The athlete, the former major winner, had lost his last six title deciders, comprising in the German tournament previously this season.
The player's retrieving approach and frequent outbursts on the playing surface had prompted observers to doubt if his skill to compete at the top level was finished.
Yet the athlete has altered his approach in the past month, making an effort to approach the net and play assertively, backed up by an better serve.
Medvedev came back from a deficit in the first set against the tricky opponent, winning four of the final five points to take the lead.
The competitors exchanged service breaks in the middle set before the challenger, attempting for his maiden ATP Tour title, took control to force a decider.
Moutet rescued four initial break points in a tight deciding set before the champion won the break to fifteen to close out the victory.
Fittingly, the winner clinched victory with a shot at the front of the court, with the Frenchman failing to control a shot after over two and a half hours.
