Here I had the TFA Dostmann 60.4508 radio wall clock found.
Unfortunately, the details of the scale in the product description were contradictory.
The size is 230 x 185 x 31 (80) mm, so a good size and from 3-4 meters legible.
Practically the tilt stand.
Operation is very simple, connect and after about 3min the time / date is displayed.
The display should not touch you, produces streaks on the display, but go away over time.
On the question that is asked here again and again: What is needed for a power supply.
You can remove all the batteries and power the clock only a power adapter.
The measured current at 4.5V and full backlight is 42mA.
A switching power supply with max. 100mA power does not exist.
I have an existing eco-friendly set to 4.5V, with max. 300mA, taken.
Is there for less than 5 minutes for Pollin or Reichelt, suitable adapter plugs is.
The clock I would not hesitate to recommend it!
