Following the successful launch of their 5548 ultra thin perpetual calendar in 1978, Audemars Piguet followed up with the sapphire open caseback in 1985 and around the same time launched the 25558 reference with the skeleton movements and openwork dial, produced in very small numbers. The total, according to scholarship, is 217 pieces made of this reference: 154 in yellow gold (like this one), 62 in platinum and 1 in white gold.
The case construction was then updated in 1988 with the reference 25668 and produced until 1993, only 205 examples of this reference were produced. 94 in yellow gold, 79 in platinum, 30 in pink gold and 2 in white gold. With less than 250 pieces made of the 25558BA & 25668BA in yellow gold, it is a collector gem and the beauty of seeing the perpetual calendar at work is also a true pleasure for the wearer, especially when setting the watch.
Rarely seen with silver registers vs the usual cream, this early example is furthermore set apart in rarity.
