Scottie Pippen -- Pimped Out $70k Diamond Watch ... With My Face On It (PHOTOS)

Scottie Pippen's watch game just got stronger -- after Hublot made the NBA legend a custom $70,000 timepiece ... complete with more than 100 DIAMONDS ... and his own face on the back!!

TMZ Sports has learned ... Pippen was gifted the watch at his 50th birthday party over the weekend ... given to him by the CEO of the company himself.

The watch is a Hublot Power in King Gold -- complete with a picture of Scottie in his #33 Bulls jersey laminated inside the case back of the time piece and valued at $70,000 ... according to Haute Time, which threw the party.

And get this ... MICHAEL JORDAN was in the flesh at the shindig to see the whole thing go down ... Michael B. Jordan, that is.

Still pretty cool. Happy birthday, Pippen.
