Oddly 1992 3592.50
Haha not oddly really, I just took a "not too risky" guess since those dials with the dropped Speedmaster "r" were phased out in exactly mid-1992, having been used previously for at least 20 or so years. Turns out your watch happens to be one of the very last ones with that dial.
Sorry for cap locks
