Amar'e Stoudemire got one hell of a birthday gift from his Miami Heat bosses and teammates -- who pitched in to buy A.S. a $25,000 watch ... TMZ Sports has learned.
Dwyane Wade, Gabby Union, Pat Riley, Alonzo Mourning and Heat owner Micky Arison hit Cipriani in Miami Sunday night for a bday celebration for the big man ... who turns 33 Monday!
We spoke with a rep for Haute Living -- which helped throw the party with Hublot -- who tells us Stoudemire received a Hublot special edition Miami Heat watch during the shindig.
"The watch retails for $24,700," the rep tells us ... "and all of the players, coaches and the owner chipped in to buy it for him."
It's nice to have rich friends.
