The famous hitmaker and Nicole Tuck always throw joint birthday parties this time of year. He turned 43 on November 26 but Nicole just turned 43 on Friday ... prompting a huge shindig thrown by Haute Living Saturday night at the Perez Art Museum in Miami for a 60-person dinner with friends and family.

While at dinner, they were surprised with these incredibly insane watches. Khaled rocked a Roger Dubuis Excalibur automatic skeleton pave. That watch runs around $106k. Nicole got a Roger Dubuis Velvet Caviar watch ... worth about $53k.

Khaled now has nearly a handful of $100k watches floating around his house. Remember, he got this sick timepiece for his 41st birthday. And, last year, Nicole commissioned Haute Living to make this watch laced with more than 600 diamonds. That one was for their son, Asahd, who was celebrating turning 1 ... sippy cups be damned.

The dual bday bash later moved over to LIV nightclub where Ciroc was flowing for Khaled's celeb pals ... including Swizz Beatz, Fat Joe, Busta Rhymes, Young Jeezy and Fabolous. We're told CIROC Black Raspberry was the drink of choice at the bash and was flowing all night.
