Of course, this thread is for GLau, our enamel lover and specialist!
Patek Philippe's ref. 5076P was first launched in 2003 and stayed in production until 2006, a short span of only 3 years with around 120 examples in total with various themes crafted with cloisonné enamel.
Each set includes four different dials on the same theme.
The platinum case measures 30 x 43 mm. Watches are powered by caliber 215 (some with small seconds, some without)
Cheers, Emmanuel
