The Welshman reached the milestone today and United boss Moyes said his squad did not let the momentous occasion pass by unnoticed.
"The lads had one or two surprises for him in the dressing-room," said the Red Devils' manager.
"One was a coach's watch. I think he was beginning to think they were pushing him out of the dressing-room!
"The players are very good. He's respected by everyone in the dressing-room because of what he's done and what he's achieved in football.
"Undoubtedly Ryan's at the top because of his longevity, the time he's played for one club, the amount of games he's played, what he's done in the Premier League and Europe.
"Every season you can look through and see Ryan Giggs moments. I just think to be playing so well at his age is terrific.
"He's a great example to young players of how you should dedicate yourself to your career, and also to players in their early to mid-30s, who think maybe they're coming to the end.
"But if you really look after yourself and train well, it can maybe go on a lot longer for you."
