Yes, Deutsches Institut für Normung. It’s the German Standards Institute. They developed the typeface DIN Time is based upon. The typeface was used for road and highway signage. The design of DIN Time was also originally inspired by these highway signs, but more so on the Pebble. Some elements has been removed for the Fitbit version. You can still see traces though, like the naming of one of the themes, Autobahn. The dashed line around the forecast is another thing. On highway signs a dashed box around a road number shows that the current road or exit leads to that road, ie. what’s coming -> forecast. Pretty far fetched, but I like it.
Does “DIN” mean anything?
