19 of Medvedev's twenty-one victories have been earned on hard courts
A resurgent the Russian player claimed his first title for 882 days with success over opponent Moutet in the competition final.
The athlete, a ex- number one, has endured a challenging season, winning just a single victory at the Grand Slams and experiencing a difficult moment at the US Open.
The player's unpredictability on the professional circuit - and issues with his serve in particular - led to him falling of the elite rankings and eventually parting ways with long-term coach Gilles Cervara.
Now working with Thomas Johansson and his other coach, the tennis star has steadily progressed in the past month - climaxing in a hard-fought three-set triumph over Frenchman Moutet.
This represents his first championship since the Italian tournament and maiden on a hard court from spring of that year.
Victory also indicates the Russian has won twenty-one titles at 21 distinct events.
"This marks the first occasion I have attended a event with my children together, so to secure a championship is really nice," commented world number 14 the champion.
"This title is in dedication of my child my daughter, because the maiden victory I got when my older daughter my daughter was delivered was for her."
The tennis star, the former major winner, had been defeated in his previous six championship matches, comprising in Halle previously this season.
His counter-punching strategy and frequent emotional displays on court had caused some to wonder if his skill to play at the highest level was finished.
However the player has implemented adjustments in the past month, attempting to come to the net and play positively, reinforced by an improved serving game.
The champion recovered from a disadvantage in the initial set against the tricky Frenchman, taking 4 of the last five games to take the lead.
The pair exchanged break points in the second set before the challenger, bidding for his initial professional title, seized the initiative to create a final set.
The opponent saved four initial break points in a competitive deciding set before Medvedev won the break to that score to secure the win.
Fittingly, he clinched the win with a point at the net, with the Frenchman incapable to handle a volley after a lengthy match.
