I remember that I acquired this watch in March 2019 at an AD in Hong Kong. It was recommended by Ben Hodinkee founder in a video as a top buy for a perpetual calendar, which was how I got to know this model. The adjustment of date/month/day/moon phase is easy with just one button (all synchronized),
I wanted to have a Sinn watch for a long time. I almost bought their tide watch a while back (I grew up near the sea). I am very happy with this MOP piece and the all black case and bracelet look better than I expected. Have a very nice weekend to you too! Take care!
