Up for grabs is an Audemars Piguet Perpetual Calendar
Reference is 25679 BA in 18k yellow gold
C series wit this model have been made in early 1990’s
I am calling it a “baby perpetual” because of its size, 30mm
This is an automatic watch with Cal. 2132 movement. Impressive to have such complication in such a small watch.
White enamel dial is damage-free.
The case appears to be unpolished and shows some patina on the gold. Original winding crown.
Caseback also appears unpolished with crisp engravings. This watch is numbered 190
Comes on original AP strap and AP 18k yellow gold buckle.
No box or papers. No documented service history. The watch functions and shows about +15 seconds on timegrapher with ~260 amplitude.
A similar example has sold at Sotheby’s in May of 2024 for about $26k USD in Geneva.
