I am very pleased with the clock. The lighting is adequate. Whoever criticizes the minute strokes in the dark not being able to see, I will give right. But by the angle I can very well estimate whether it's "6 or 8 after" because the 5 minute mark, like the hand in the dark light visible even slightly. The clock can be einstellten so that the lighting automatically goes on when it is dark and you rotate the wrist so that it looks at the clock. Very convenient! The barometer indicates something and altitude changes while hiking can be read. Must both but be calibrated. The temperature sensor is only for use when used on the clock, waiting for a while, because this drives the body temperature measurement result upwards. Compass will also work approximately, but is distracted as any other compass by magnetic fields nearby. If the pointer in front of the screen and you want to read something here but there are currently no function temporarily turn away the hand. I manage by switching to a different time zone. Here you can switch back and forth and best select a zone that offers and discounts for 30 minute difference, because so does the minute hand turns away. How many years Casio is not a guide to print in position with a larger font. While that is downloadable as a PDF file, but not printable. It lacks large parts of the text and images.
