(TMZ) -- DJ Khaled is hooking up his famous son, Asahd, with two things for his 1st birthday -- a sick diamond-studded watch, and a ton of patience ... 'cause he can't even wear the watch yet.

Khaled's wife, Nicole Tuck, commissioned Haute Living -- which also threw the birthday bash -- to make a VERY nice watch for Asahd. The piece is laced with more than 600 diamonds which weigh in at 11.65 carats ... all for just over $100k.

TMZ was told the watch is a Franck Muller model in rose gold, with Asahd's name and birth date engraved on the back. It's also adult sized, and seeing as how Asahd just turned one ... he probably won't be ballin' out anytime soon. Good to know it's waiting on deck though.

You da best, mom and dad!
