Our friend Quattro initiated a thread about Patek WT, and the 5110G Proto came out of the wood.
So, I did a research and fell on these photos, most probably to be credited to Sothebys.
To be honest, I am not impressed at all by this unfinished dial. And a detail bugs me. The 5110 was issued in year 2000. How come this prototype was manufactured in 2003? I wondered it if didn't house a special version of the movement, as well, but it is said " Cal 240HU ", so apparently nothing special, here.
This piece remains a mystery, to me.
Best,
Nicolas
