Very beautiful 3940R indeed. Although any perpetual dial needs to be busy, the 3940 is a quiet perpetual that is so classic. I'm also trying to find a classic rose gold (creme/off white/opaline dial) dress-type watch that will survive the fads/swings/preferences of years to come. 3940R is on my short list. Also the 5170R-001. Perhaps an understated Annual Calendar. For a classic dress watch I'm looking at the type of complications that Patek has made for a couple generations or more. Love the manual wind, also the thinner automatics. Nothing too chunky or nouveau that might look dated/period 15 years from now.
I think you absolutely nailed it with the two watch collection you share in this post. Congratulations on your fine taste Libor.
Best,
Robert
