From its launch until its discontinuation 25 years later, the gold version of the Royal Oak series Sunday Calendar Lunar Watch Ref. 25594BA only offered three dial styles. The dials were a light gold color before 1996, complementing the golden tones of the case, strap, hour markers, hands and moon pattern. The week and calendar display rings remained a deep golden color until 2000, when they were changed to the same color as the dial. ~
