I see that you have the older version with 32 jewels; the new ones AFAIK have 29. The movement you have there is also endowed with a Pt 950 rotor, which has a slightly heaviver mass than the Au 750 ones concequently the winding efficiency is potentially higher per movement. They are similar to the ones on Parmigiani as well, as the original movment designer was indeed Micheal Parmigiani. That Guilloche by Metalem is sublime. Enjoy, these are beaufiul watches and stunning movements.
From what I've seen in the wild, though, Chopard almost certainly didn't produce the full run of 1860. In fact, I'm curious to know the highest caseback number (out of 1860) that anyone has seen for each of the 1860/2 gold models -- rose, white, and yellow. Has anyone seen a caseback number higher than 1000/1860 for any of these models? Or even 500/1860?
So many people talk about watches like lifetime purchases, but most only last a few years before being sold or traded for some reason or another. I'm glad you still enjoy it as much after two decades. I hope it's still here in 2045.
Always nice hearing from you, Tim -- hope you're well. Having a small wrist makes a watch like this easier to enjoy -- when the proportions are just right.
