Most perpetual calendars ask you to study them; this one you simply glance at.

The white dial is the whole argument: it gives every indication enough room that the date, the day, the month and the moon phase resolve in a hallway light, without angling your wrist toward a window to be sure of what you are looking at. That readability changes how you live with the complication, because a calendar you can actually read becomes something you use rather than something you own. The steel case and silver stainless steel bracelet keep it from feeling precious, which matters more than it sounds; this is a dress watch you can wear on an ordinary Tuesday and not think twice about it. There is a particular German restraint at work here, where nothing on the dial exists for decoration and the complexity stays behind the scenes instead of announcing itself. Once it is set, it keeps track without you, and the moon phase becomes the thing you find yourself checking for no reason at all. It is the rare complicated watch that asks nothing of the wearer beyond putting it on.
