Everybody needs a friend like Odell Beckham Jr. ... 'cause the Cleveland Browns superstar just gave his teammate and best bro Jarvis Landry an incredible $110k watch for his birthday!!
TMZ Sports has learned ... OBJ wanted to do something extra special for Landry's 27th birthday on Nov. 28, so he hooked him up with a Patek Phlippe 5980 Nautilus ... and it's beautiful.
We're told Odell hit up his go-to guy Gabriel The Jeweler to make it happen ... and the dude came through in the clutch just in time for Landry's big day.
