The window in the cover is very pretty with a clock displayed. It also allows you to call, take photos without opening the case. Touch is also nice and thickness remains very moderate.
So we have much choice. Take the 345 model by adding a little thick on the phone or model 340 for 15 euros more to keep the incredible thinness of the phone.
Flat, after just 1 week of use, the cover does not close completely by the charger and the circular hole leaves dust spots on the screen. Not sure which phone aging well with this case.
