Following the discontinuation of ref 5236, we can notice that all recent "simple" perpetual calendars are offered at a huge discount on the secondary market: the 5236 itself, the 5320, the 5159, even the 5140. It seems that only 5740 is appreciated, but this is a different story.
I personally think this is the most fantastic complication, but clearly the market thinks different.
Any thoughts?
Have a lovely sunday
