Nineteen of the Russian's twenty-one titles have been achieved on hardcourt
A comeback Daniil Medvedev claimed his maiden trophy for 882 days with success over Frenchman Moutet in the competition title decider.
The Russian, a former number one, has had a torrid year, achieving just one match at the major tournaments and undergoing a difficult moment at the US Open.
Medvedev's inconsistency on the tennis tour - and issues with his serve in specific - led to him falling of the top ten and ultimately separating with long-time trainer his previous coach.
Presently training with Johansson and Rohan Goetzke, he has steadily improved in the last few weeks - peaking in a tightly fought 7-5 4-6 6-3 triumph over opponent Moutet.
This represents Medvedev's first title since the Rome competition and first on a hard court from spring of that year.
The win also means the Russian has won twenty-one championships at twenty-one various tournaments.
"For the first time I'm at a tournament with my two daughters simultaneously, so to win a trophy is particularly special," stated world number 14 Medvedev.
"This championship is in dedication of my second daughter Victoria, because the maiden victory I won when my first daughter Alisa was delivered was for her."
The athlete, the former major winner, had failed in his previous six finals, comprising in Halle in the past months.
His counter-punching play style and recurring reactions on the tennis court had caused some to wonder if his capacity to compete at the elite level was concluded.
However the 29-year-old has implemented adjustments in recent weeks, striving to advance forward and perform positively, backed up by an enhanced serving game.
Medvedev came back from a deficit in the initial set against the difficult opponent, winning 4 of the last five exchanges to gain the advantage.
The pair swapped break points in the middle set before the Frenchman, bidding for his maiden professional championship, took control to force a final set.
The opponent rescued four early opportunities in a tight final set before Medvedev won the break to fifteen to secure the win.
Appropriately, the winner secured the title with a rally at the net, with his opponent incapable to manage a volley after a lengthy match.
